About this service
A slide-in range is a cooktop and an oven sharing one chassis. We service it that way.
Bosch slide-in ranges are increasingly the spec on Westside renovations and OC family kitchens where the cleaner cabinetry line of a single 30-inch unit beats the look of a separate cooktop + wall oven. The trade-off: when something fails, our techs are usually working in tighter quarters than a separate-cooktop service call, and access to either side often means partial disassembly that affects the other. We approach every Bosch range visit as a combined system, diagnose the symptom on whichever side it presents, but assess both halves before quoting.
Three platforms, three failure trees. HEI induction (HEI8054U, HEI8056U) is electronic-dominated: inverter boards, touch UI, communication faults, glass-top damage. HRI dual-fuel (HRI8082U) splits the diagnostic between gas-burner mechanics on top and electric-oven heating on the bottom. HGI all-gas (HGI8054UC, HGI8056UC) is mechanical-dominated: spark modules, individual igniters, gas valves, oven hot-surface igniter, door latch interlocks. Knowing which platform you have is step one, model number on the inside-door trim plate confirms it.
Most calls we see are 4-to-9-year-old units past the 2-year warranty. HEI: communication codes (E-001, E-007) cluster around year 5-7, inverter board failures year 7-9. HRI: oven bake element year 8-12, convection fan motor year 9-13. HGI: spark module replacement year 8-12, individual igniters ongoing across the life of the unit. Glass-top damage on HEI can occur at any age, almost always impact, occasionally thermal shock from a cold pan dropped on a hot zone.
Models we service
Bosch slide-in range model families
800 Series HEI8054U, Induction Slide-in 30"
HEI8054U · induction · 30" · 240V/50A
Premium 800 Series induction slide-in. 5 induction zones with FlexInduction-capable pairs, AutoChef temperature regulation, 17 power levels, electric convection oven below. Common in Westside luxury renovations 2021+ where the homeowner wanted induction without committing to a separate Benchmark cooktop. Service tree is dominated by inverter board and touch-control failures, plus the standard electric-oven failure modes (element, sensor, fan).
800 Series HRI8082U, Dual-Fuel Slide-in 30"
HRI8082U · dual-fuel · 30" · gas top + electric oven
5 sealed gas burners on top, electric convection oven below. The owner-popular spec for households that want gas responsiveness on the cooktop and the more even heat profile of an electric oven for baking. OptiSim low-simmer burner is a service item, its dedicated valve and orifice differ from the regular burners. Oven side shares the bake element / broil element / convection fan platform with HEI ranges and HBL wall ovens.
800 Series HGI8054UC, Gas Slide-in 30"
HGI8054UC · all-gas · 30" · NG or LP convertible
All-gas 5-burner cooktop with gas convection oven (hot-surface igniter, gas regulator, oven thermostat). Common in pre-2018 LA homes where gas infrastructure is already in place and there's no 240V/50A capacity for an electric range without panel work. Service tree is mechanical: spark module across all burners, individual igniters per burner, oven hot-surface igniter, gas valves, door latch interlock for self-clean cycle.
500 Series HEI8056U, Entry Induction
HEI8056U · induction · 30" · 240V/50A
Entry-tier induction slide-in. Fewer touch features than 800 Series (no Home Connect on most builds, simpler control panel, no FlexInduction zone combining), but the underlying inverter board family is the same, repair parts are similar cost to 800 Series despite the lower purchase price. Common in mid-tier LA condos and OC family kitchens where induction was specified but Benchmark wasn't in budget.
500 Series HGI8056UC, Entry Gas
HGI8056UC · all-gas · 30" · NG or LP convertible
Entry-tier gas slide-in. 4 sealed burners, simpler control panel, smaller oven cavity than 800 Series HGI8054UC but same core gas architecture. Shared parts platform with the 800 Series gas range, spark modules, igniters, gas valves cross-reference. Reasonable repair economics over the unit's service life.
Model number prefix key: HEI = induction range. HRI = dual-fuel range (gas top + electric oven). HGI = all-gas range. The first digit after the prefix designates series tier (8 = 800 Series, 5 = 500 Series). Newer units (2022+) carry suffix letters indicating finish and Home Connect capability, those don't affect the underlying repair parts platform.
Common failures
The ten things that break on a Bosch slide-in range
1. Induction zone doesn't heat (HEI), cookware first, then inverter
Most common HEI service call. Step 1, free, 10 seconds: place a magnet on the bottom of your pot, sticks firmly, the pot is induction-compatible; doesn't stick, the pot is aluminum or copper and will never heat on induction. About 30 percent of "my induction range doesn't work" calls resolve here. Step 2: confirm child lock isn't engaged on the touch panel. Step 3: if cookware and lock check out and one specific zone won't heat while others work, the inverter board for that zone has failed, replacement $485-$685. We always run the cookware test before ordering parts.
2. E-001 or E-007 communication faults (HEI)
Touch control board can't talk to the inverter assembly under the cooktop. Reset procedure first: kill the breaker for a full 10 minutes (induction boards have larger capacitors than dishwashers, 30-second reset isn't enough). About 15 percent clear at this step at no cost. If persistent, reseat the harness between touch control and the induction module, degraded contacts from years of vibration are common (free if it's just a reseat). If the harness checks out, touch control board $385-$545 or single inverter $485-$685 depending on which side of the bus is failing.
3. Glass top cracked (HEI induction)
Impact damage from a dropped pan or utensil is the #1 cause; thermal shock from a cold pan dropped on a hot zone is secondary. Once cracked, full top replacement is the only fix, Bosch ceramic glass cannot be repaired. Glass alone $685-$985 by model; total visit with the pull-replace-reset labor lands $1,150-$1,400 typically. Don't continue cooking on a cracked top, cracks expand under thermal cycling and can fail suddenly mid-cycle. We confirm exact model number before ordering since 30" HEI8054U and HEI8056U use different glass profiles.
4. Burner won't ignite (HGI / HRI gas side)
Diagnostic by sound. Turn the knob, listen, clicking sound means the spark igniter is firing (issue is elsewhere). No clicking means igniter or spark module has failed. Clicking but no flame: burner port clogged with grease or food debris (clean with brush, $85 flat or free DIY), misaligned knob blocking gas flow (free realignment), or no gas supply to that burner. No clicking at all: igniter per burner $95-$145, spark module that drives all burners $285-$385. Manual light fallback works (long match or BBQ lighter) while waiting for service, same as any gas cooktop or range.
5. Continuous sparking after the burner has lit (HGI / HRI)
Common, and commonly misdiagnosed by owners as a failed spark module. Often it's actually water intrusion: a spilled liquid through the burner knob area shorted the spark switch and the module is "stuck on." Fix: kill the breaker, let the unit dry 24-48 hours, reassess. About 60 percent of continuous-spark calls resolve at this step at no cost. If the spark module actually failed (less common), $285-$385 replacement. Bosch and Viking gas cooktops use similar spark module architectures, so the diagnostic and resolution pattern is the same on both.
6. Oven door latch / self-clean safety interlock failure
The oven door latch is a service item across all three platforms (HEI, HRI, HGI). The latch motor engages a mechanical pin that locks the door during self-clean cycles when the oven runs at 800-plus degrees. When the latch motor fails, two symptoms: (a) door won't unlock after self-clean has finished, oven displays a lock error; (b) self-clean refuses to start because the controller can't confirm the latch engaged. Replacement assembly $245-$385, labor 45-60 minutes. We see this most often on HRI dual-fuel because the electric oven runs the highest self-clean temperature and the latch sees the most heat exposure.
7. Convection fan motor failure (HEI / HRI ovens)
Convection oven on HEI and HRI uses a small fan motor mounted at the rear of the oven cavity to circulate hot air. After 9-13 years of regular use, the fan bearing wears and the motor either runs noisily, intermittently, or stops entirely. Symptoms: convection cooking comes out unevenly (some areas overcook, others undercook), or you hear a grinding/clicking sound during operation, or the fan doesn't run at all in convection mode. Replacement motor $245-$345 plus 60-min labor. Conventional bake (no fan) still works during a convection-only failure, useful bridge while waiting for the part.
8. Oven won't reach temperature, bake or broil element burnout
Standard service item on the electric ovens (HEI and HRI), heating elements eventually burn out around year 8-12. Diagnostic is straightforward: visual inspection (broken or burned-through coil = obviously failed; intact-looking element can still be electrically open). Multimeter continuity test from the rear of the oven confirms, functional element reads 15-25 ohms, failed element reads infinite. Replacement bake element $185-$285, broil element $185-$285, 30-45 min labor. On HGI all-gas, the equivalent failure mode is the oven hot-surface igniter, same age range, same symptom (oven not heating), but igniter $145-$215 plus the gas-line safety check during install.
9. Oven temperature sensor drift (calibration off)
Owner symptom: "my oven is running too hot/cold", set 350°F, food cooks like 375°F or 325°F. Cause is usually the oven temperature sensor (a small two-wire RTD probe at the back of the cavity) drifting from its factory calibration. Sensor replacement $145-$215. Sometimes the BAY control board has drifted instead, board calibration $385-$545. We always check sensor first because (a) it's the cheaper fix, (b) sensor drift is significantly more common than board drift. On rare occasion, the issue is just calibration offset accessible through the user menu, free fix at diagnostic if that's all it is.
10. BAY control board / UI failure
Catch-all for "the range isn't responding correctly to inputs", touch screen unresponsive, display showing partial or wrong information, oven set to one temperature but heats to another, mode selection not working. The BAY (or UI on newer models) is the central control board behind the touch interface. Replacement $385-$545. Before ordering: full breaker reset 10 minutes (clears latched faults), inspect harness from the BAY to the rest of the unit, confirm it's the board and not a sensor or relay downstream. About 5-10 percent of "control board failure" service calls resolve to a downstream component instead, saves the owner $300+ when we catch it on diagnostic.

Bosch range jobs across the territory
Beverly Hills, HEI8054U, single induction zone non-heating
2022 install in a Beverly Hills kitchen renovation. Front-left zone stopped heating; other three zones working normally. Cookware magnet test passed (induction-compatible cast iron), child lock not engaged, no error code on display. Diagnosed as front-left inverter board failure. Replaced inverter, ran calibration cycle, confirmed all four zones at full output. $625 parts and labor on a 90-minute visit. Owner had been bridging with a portable induction burner on the counter, back to normal cooking same day.
Pasadena, HRI8082U, oven not reaching temperature
2019 dual-fuel slide-in in a Pasadena home. Owner set oven to 375°F, food consistently undercooked across multiple bakes. Diagnostic showed both bake element ohms-out (functional) and convection fan running. Pulled oven temperature sensor, read 1,150 ohms at room temp, factory spec is 1,080 ohms ±2%. Sensor drift confirmed. Replaced sensor, ran calibration, baked test piece, temperature held within 5°F of setpoint. $185 parts and labor on a 60-minute visit. Owner declined the BAY board replacement we'd flagged as a fallback, sensor swap fully resolved.
Newport Beach, HGI8054UC, intermittent burner ignition
2020 all-gas slide-in in a Newport Beach kitchen. Two of five burners required multiple knob turns to light; other three lit on first try. Diagnostic: spark module clicking on all burners (module functional), igniter electrodes on the affected two burners showed corrosion at the spark gap. Replaced both individual igniters, cleaned the burner cap seats, confirmed all five burners lit cleanly on first turn. $245 parts and labor. The OC coastal salt environment accelerates igniter corrosion versus inland kitchens, we see this pattern on Newport Beach, Laguna, and Manhattan Beach gas cooktops more often than equivalent inland units.
Where we go
Bosch range service across Greater Los Angeles
Slide-in range concentration runs heaviest in Westside renovations, Beverly Hills, Brentwood, Santa Monica, Pacific Palisades, and in newer OC family kitchens, Newport Beach, Costa Mesa, Irvine. Pasadena and the foothill districts skew toward dual-fuel HRI specs in 2018+ remodels. Inland Empire and Riverside coverage is growing as new construction in Rancho Cucamonga, Corona, and Temecula increasingly specs induction slide-in over older gas wall-oven plus cooktop combos.

Bosch range repair, common questions
Induction vs. dual-fuel vs. all-gas?
HEI induction is electronic-dominated (inverters, touch boards). HRI dual-fuel pairs gas burners up top with electric oven below, split diagnostic. HGI all-gas is mechanical (spark modules, igniters, gas valves, hot-surface oven igniter). Each platform has a distinct failure tree; we carry parts and training for all three.
Do you service Bosch dual-fuel ranges (HRI8082U)?
Yes. 30-inch slide-in, 5 sealed gas burners on top, electric convection oven below. Most HRI calls are oven-side: bake element burnout year 8-12, convection fan motor year 9-13. Door latch / self-clean interlock is also frequent.
What does E-001 / E-007 mean on my HEI induction range?
Communication fault, touch control can't talk to inverter assembly. Try a full 10-minute breaker reset first (induction boards need it longer than dishwashers). About 15% clear at no cost. If persistent, harness reseat free, touch board $385-$545, single inverter $485-$685.
How long does a glass top replacement take?
2-3 hours total. Glass alone $685-$985 by model, full visit including pull-replace-reset $1,150-$1,400. Confirms exact model number before ordering, HEI8054U and HEI8056U both 30" but use different glass profiles. Lead time 3-7 business days.
Are slide-ins harder to repair than separate cooktop + wall oven?
Slightly. Same components, but tighter access, getting to oven control often means partial cooktop disassembly and vice versa. Pulling a 200-plus-pound slide-in is a two-tech lift. Same diagnostic fee; complex repair labor can run 30-60 minutes longer than equivalent separate-unit fix.
Do you stock parts for 800 Series Bosch ranges?
Common wear parts on the truck: igniters, spark modules, bake/broil elements, oven sensors, door gaskets, convection fan motors. Inverter boards, glass tops, BAY control boards, door latch assemblies come 2-3 day from Bosch parts distribution. 500 Series shares core parts with 800 Series.
Bosch range malfunctioning? Call the branch closest to your home.
Same day available. $89 diagnostic, waived with repair. Cookware magnet test and child lock check included free on every induction call.
