Re: indesit iwme126 wont drain
The little permanent magnet pump is prone to failure. It may appear to run beautifully when it’s not under load (empty) but any amount of water and it won’t shift it. If the impeller has the slightest lateral movement indicates the bearings are knackered. A new pump the solution.
Also the ball valve in the sump hose can be a serious issue when liquid detergents are used. The valve gets sticky.
Another thought is perhaps a coin is stuck in the drain pipe beyond the pump and acts as a valve? Open one minute, closed the next. Worth a thought.
Finally, it’s an Indesit. They don’t last long, the mechanics are weak and the electronics total c-rap.
I hope that helps you? 😀
