01 · What we service
A commercial undercounter dishwasher that won't drain, fails sanitization spec, or shows mid-service failure in LA bar + prep station operations usually traces to one of three root causes our techs at Same Day Appliance Repair diagnose first across WeHo + Arts District bar operations, Santa Monica beach-adjacent bars, restaurant prep stations, café operations, and Beverly Hills hospitality back-bar installations running Hobart LXe / LXeR / LXn / LXnR, CMA Energy Mizer, Champion UH-150, Jackson AvengerLT / JP-24, Hoshizaki commercial undercounter models. (1) Door gasket compression set year 5-7 (#1 LXe service item) — gasket wears with continuous thermal cycling, water sprays out during wash cycle. $180 to $340 gasket replacement. (2) Drain pump year 7-9 — pump motor failure means standing water, cycle won't complete. $280 to $440 drain pump replacement. (3) Door switch or door latch sensor year 5-7 — controller doesn't recognize door fully closed, won't initiate cycle. $140 to $240 switch replacement. Plus fill solenoid year 7-9 ($200-$340) and heating element year 6-8 ($240-$380). $120 commercial diagnostic at Same Day Appliance Repair, waived with repair. Undercounter dominant in bar + back-of-house prep station operations.
Undercounter commercial dishwashers fit under bar counter or café prep counter, 30 to 40 racks per hour throughput. Bars, cafés, small restaurants, mobile kitchens. NSF 184 commercial rating distinguishes them from residential undercounters: 208V or 240V three-phase electrical, faster cycles (90 seconds to 4 minutes), higher wash temps, integrated chemical sanitizing or high-temp final rinse.
Four platforms dominate LA bar and café installs: Hobart UH series and LXeR (ITW Food Equipment Group, the most common premium undercounter), CMA Energy Mizer (Cleveland-based commercial dishwasher specialist), Champion UH-150 (Ali Group, sister brand to Scotsman ice and Beverage-Air refrigeration), Jackson Conserver (Hoshizaki America acquired). Plus Insinger Speeder on legacy installs.

02 · Typical undercounter failures
Across LA County commercial undercounter dishwasher service calls our techs at Same Day Appliance Repair dispatch — WeHo + Arts District + Santa Monica bar cluster running Hobart LXeR rackless variants for glass and small-ware operations, restaurant prep station undercounter installations, hotel back-bar operations (DTLA hospitality, Beverly Hills luxury), café operations with Jackson AvengerLT + JP-24, plus food truck commissary kitchens — the failure distribution clusters predictably. About 30 percent door gasket compression set (year 5-7, $180-$340, #1 LXe service item). 20 percent drain pump (year 7-9, $280-$440). 15 percent door switch or door latch sensor (year 5-7, $140-$240). 10 percent fill solenoid (year 7-9, $200-$340). 10 percent heating element (year 6-8, $240-$380). 10 percent wash arm bearing (year 5-8, $180-$320). 5 percent control board faults on year 10+ Hobart LXe units ($600-$1,100). LADWP hard water 8-12 grains/gallon makes annual descale critical for undercounter operations — daily filtration not enough alone.

08 · FAQ
A commercial undercounter dishwasher that won't drain usually traces to one of three causes our techs at Same Day Appliance Repair diagnose first across Hobart LXe / LXeR / LXn / LXnR, CMA Energy Mizer, Champion UH-150, Jackson AvengerLT / JP-24, and Hoshizaki commercial undercounter installations. (1) Drain pump motor failure year 7-9 — pump motor bearing wear or impeller failure means pump won't move water. $280-$440 drain pump replacement, 45-60 minutes. (2) Drain pump impeller jam — debris stuck in impeller prevents rotation, often resolves clearing debris during the $120 commercial diagnostic. $180-$280 service. (3) Drain line clog or backflow — kitchen drain plumbing issue rather than machine fault. Plumbing contractor scope, our techs verify pump operates correctly with alternate drain test. Plus drain solenoid valve year 7-9 ($180-$320) and controller drain cycle fault on year 10+ units. Our techs verify pump motor amp draw + impeller free rotation + drain line backflow test on every won't-drain call.
Door gasket compression set is the #1 Hobart LXe / LXeR / LXn / LXnR service item across LA commercial undercounter installations. Gasket wears with continuous thermal cycling from 180°F final rinse exposure, loses compression seal, water sprays out during wash cycle. Year 5-7 typical wear curve. $180-$340 gasket replacement, 45-60 minutes. Plus door switch wear (year 5-7, $140-$240) often paired with gasket replacement. Other top LXe / LXeR service items: drain pump (year 7-9, $280-$440), fill solenoid (year 7-9, $200-$340), heating element (year 6-8, $240-$380), wash arm bearing (year 5-8, $180-$320). LXe rackless variant (LXeR / LXnR) common in WeHo + Arts District bar cluster for glass and small-ware operations — same failure pattern profile as standard LXe. ITW Food Equipment Group Ohio parts pipeline 5-10 day standard ship; common LXe parts stocked on truck for first-visit completion.
Most common cause is a worn door gasket failing the door switch interlock (year 4 to 7 typical). Less common: water inlet valve degraded, drain pump clogged with debris, control board fault. We diagnose with the front access panel removed, $120 commercial diagnostic.
Yes. These three platforms cover roughly 75% of our undercounter calls. Plus Jackson Conserver. We carry common door gaskets, wash pump impellers, drain pumps, and detergent dispenser solenoids on the van for these models.
Residential undercounter dishwashers run on 120V, cycle in 60+ minutes, lower wash temp, NSF residential rating.

Different repair scope.
