Frequently asked questions
Why is my dishwasher filling with the power off?
The inlet valve is stuck open mechanically. Shut the water supply valve and call a technician.
Is FE dangerous?
It can be. Unchecked overfilling floods the kitchen, so shut the water off first and troubleshoot second.
Can high water pressure cause FE?
Yes, very high pressure can push past a weak inlet valve. A plumber can check your pressure.
