The 5 free checks
Start at the top. Unplug the machine first.
- 01
Press Cancel twice to clear the code.
- 02
Confirm both the hot and cold supply faucets are fully open.
- 03
Inspect the inlet hoses for kinks.
- 04
Inspect the screens where the inlet hoses connect for clogging.
- 05
If there is water in the machine rather than none, check the drain instead of the fill — and look for a hose leak or a siphon.

If none of that fixed it
Past that, PartSelect describes component testing on a machine that has to be unplugged first — the inlet valve, pressure switch, drain pump, flow meter and central control unit, with resistance measurements on the flow meter. That is technician work, not a free check.
