Basic checks
- Wait for the washer lock-out or drain-pump routine to finish.
- Confirm the washer water supply valves are on.
- Check visible inlet hose routing for kinks or pinching.
- Confirm the supply valve is fully open; if flow still seems weak, stop before removing hoses or screens.
- Inspect visible inlet hoses for kinks or freezing; if routing is restricted, correct it before retrying.
- Watch the next fill attempt from nearby; if little or no water enters, pause the cycle and stop retries.
Reset or retry steps
- Retry only after the water supply is confirmed on and any timed lock-out has ended.
When to call a technician
- Call service if the water supply is on and the error returns.
- Call service for suspected pressure sensing, valve, or control faults.
Before approving a paid visit, check warranty status and reviewquestions to ask before repair.
