In detail

01

Won't drain — first steps

  • Cancel the program and wait 2–3 minutes.
  • Open the door: water above the filter means a drain issue.
  • Remove and rinse the bottom filter and mesh.
  • Check the drain hose isn't kinked behind the unit or at the sink trap.
  • Run a short cycle again.

If water remains with humming — likely drain pump or valve. Don't open the housing — water + 220 V is dangerous.

02

Why it won't drain: pump, valve, aquastop

The drain pump empties water after washing. Worn impeller, debris (bone, glass chip), or seized parts stop it.

Overflow triggers if water stays — level sensor blocks a new cycle; error light may blink.

Aquastop inlet hose may shut water after a leak event — check its indicator. Our technician tests pump, hoses, and electrics on site; repair from ~150–200k UZS after inspection.

03

Poor wash — not just "more detergent"

  • Clogged spray arms — upper rack gets no pressure.
  • Low temperature — bad heater or thermostat; grease won't dissolve.
  • Bad loading — plates block jets.
  • Hard water — salt and rinse aid needed.
  • Eco mode — heavily soiled loads need intensive cycle.

Clean arm holes carefully with a toothpick — don't enlarge them. If quality doesn't return after filter and arms — check circulation pump or heater.

04

DIY vs pro

OK yourself: rinse filter; check hoses; scrape plates; hotter program; add salt and rinse aid.

Not DIY: removing drain pump, heater or board swap, opening aquastop. Risk of flooding or short circuit.

05

When to call urgently

  • Water won't drain twice after filter clean.
  • Grinding or knocking at the pump.
  • Leak under door or behind unit.
  • Burning smell, breaker trips.
  • Cold greasy dishes after intensive wash — suspect heater.

AlexProService ~1 hour, 8:00–22:00 daily. Diagnostics free with repair. Fixed quote before work.

06

Prevention

Clean filter monthly. Every six months — spray arms and door seal. Quality tablets; in Tashkent salt is essential with hard water.

Don't load unmarked aluminum or items that fall through the mesh into the pump.
