Worth repairing?

Usually free

It's almost always the filter, the hose or foam.

Can you do it yourself?

Easy

30 minutes, plus cooling time

Before you start

  • Unplug it before you touch anything inside.
  • Turn the tap off before you undo any hose or filter.
  • If it stopped mid-wash, let hot water cool before you drain it.

What to check, in order

  1. Clean the pump filter

    Unplug it. If it stopped during a hot wash, let the water cool first. Drain the water into a tray, then clean the filter and turn the pump blade with a pencil to check it moves freely.

  2. Check the hose

    No kinks, no more than 10 cm into the drain, and the drain 60 to 100 cm above the base of the machine.

  3. Check the sink trap

    Or put the drain hose into a sink for one wash to rule out your plumbing.

  4. Remove the foam

    Scoop it out of the drum. Too much detergent makes foam that can block the water level system.

  5. Let the pump cool

    Switch the power off for 1 to 2 hours so the pump's thermal cut-out can reset.

  6. Run a hot wash

    Without detergent, to clear the residue.

When to call an engineer
