A dishwasher that won't fill usually has a closed tap, a kinked inlet hose, or a tripped aquastop on the hose end.
Likely causes, ranked
- Tap off or aquastop tripped Most likely — The aquastop valve on the hose end can latch shut after a leak; the tap may be off.
- Kinked inlet hose Likely — Hoses crushed behind the machine restrict flow.
- Blocked inlet mesh filter Likely — Grit collects in the mesh inside the hose nut.
- Failed inlet valve Less likely — Electric valve failure stops all fill.
First checks
- Confirm the tap under the sink is fully open.
- Check the inlet hose is not kinked behind the machine.
- If the hose has an aquastop block, check for a leak indicator or dampness at the valve.
- Turn off the water, clean the mesh in the hose nut, and reconnect.
Safety
Turn the water off before disconnecting anything. If the aquastop has tripped, do not force it — the hose may need replacing.
Call a professional when…
Call a professional if the machine still will not fill with a clear, open supply — the inlet valve or aquastop needs replacing.
