What we fix in Minneapolis

The Minneapolis repair mix

7E — WaterWall reflector code (Samsung-specific)

Samsung WaterWall dishwashers use a moving reflector bar across the tub floor instead of spray arms. 7E means the bar didn't park at the home position — a piece of food or a fallen utensil jammed the track, or the drive motor failed. First fix: pull the bottom rack, lift the reflector bar, clear any debris from the track, and run a Self Clean cycle. If 7E returns, the WaterWall drive motor needs replacement ($345–$485).

LC / LE — leak detector

Samsung's leak sensor sits in the base pan. LC / LE means water hit it. Common leak paths: the door gasket (bottom corner), the sump-to-tub gasket, and the drain pump volute O-ring. Dry the pan, dye-test, replace the leaking part. Don't reset and re-run — the leak will trip again. $245–$385 all-in.

5E / 5C — drain fault

Same diagnostic order as every dishwasher: disposal knockout plug still in place (free fix, common on new disposal installs), clogged sump filter, drain hose kinked or clogged, drain pump impeller jammed by broken glass or label paper. Pump replacement $245–$365.

Field-service notes on dishwasher repair

On dishwasher repair, we keep the diagnostic tight because the failure catalog on this brand is well-documented. Well water in the outer western suburbs (Minnetonka, Wayzata, Orono) adds iron and manganese loading that plugs ice-maker inlet screens and dishwasher wash-arm nozzles inside 18 months without a softener.

Because this page focuses on 7e — waterwall reflector code (samsung-specific), our tech opens the call by isolating that subsystem before touching anything else. Wear parts (belts, pumps, igniters, valves) ship from our truck stock; boards and sealed-system parts are OEM-only from Marcone or the manufacturer's direct distributor. The $149 residential diagnostic is credited toward the repair if you approve; if you don't, you pay only the diagnostic and we leave a written scope. Every completed repair carries a 1-year parts and labor warranty in writing. The section above covers the specific failure surface — samsung waterwall dishwashers use a moving reflector bar across the tub floor instead of spray arms.

We stock the top-30 wear items for this brand on the truck, so most first-visit repairs close same-day. We're EPA 608 certified for sealed-system and refrigerant work, licensed and insured in Minnesota, and every tech carries a factory diagnostic laptop for brand-specific service modes. If the model is out of parts support, we'll say so on the first call and refund the diagnostic — that's the honest read on a repair-vs-replace decision, and it's the same read we'd give a family member calling about the same dishwasher.

FAQ

Minneapolis questions, answered

  • What does 7E mean on a Samsung dishwasher?

    7E is a WaterWall code — the moving reflector bar didn't park at home position. Pull the bottom rack, lift the bar, clear any debris from the track, and run Self Clean. If 7E returns the drive motor needs replacement, $345–$485.

  • What does LC or LE mean on a Samsung dishwasher?

    LC / LE = leak detector tripped. Water reached the base-pan sensor. Common leak paths: door gasket, sump-to-tub gasket, drain pump O-ring. Find and seal the leak — don't just reset. $245–$385.

  • What does 5E mean on a Samsung dishwasher?

    5E (sometimes shown as 5C) = drain fault. Check the disposal knockout plug first, then the sump filter, then the drain hose. Drain pump is the last cause. Free fix in ~40% of cases.

  • What does OE mean on a Samsung dishwasher?

    OE = overflow. The level sensor sees too much water — inlet valve stuck open or the level sensor itself failed. Turn off the supply valve immediately and call us. $245–$365.

  • How much does Samsung dishwasher repair cost?

    Most Samsung dishwasher repairs land $245–$485 all-in. Drain pump $245–$365. Inlet valve $225–$285. WaterWall motor $345–$485. Leak repair $245–$385. Control board $325–$465. The $149 trip fee is waived when you approve the repair.
