How to Fix / Troubleshooting

Safety first: Turn off power and close the water tap before disconnecting hoses.

Verify water pressure: Open a nearby faucet and confirm strong flow. If household pressure is low, contact your water supplier.
Fully open tap: Ensure the dishwasher’s supply tap is fully open and not a self-piercing type valve, which can restrict flow.
Clean inlet filter: Unscrew the Panasonic inlet hose from the tap and clean the small mesh filter. Also check the filter at the valve end if present.
Check inlet valve coil: With power off, access the inlet valve and measure coil resistance. A reading of infinite resistance indicates a failed coil.

If H20 persists with good water pressure and clean filters, replace the water inlet valve assembly.
