- Check for frozen pipes in winter months
Frequently Asked Questions
What is the difference between F10 and F12?
F10 usually means no water, while F12 often indicates slow or inconsistent water flow.
Can I still use my machine with F12 error?
No — the machine may stop mid-cycle or fail to wash properly.
What should I check first for F12?
Start with the water supply, inlet hose, and filter mesh.
💡 Pro tip: If your machine fills slowly then stops, the inlet valve is likely weakening.
