Re: Hotpoint wd420G flashing lights
It helps if you give us the lights by number from top down, however there is only one code I can see that uses four lights, is it the top four?
If so then you have an F15 fault. The heater relay on the main PCB is possibly faulty. The Indesit circuit boards on these machines are very flaky indeed.
Due to the ridiculous system the Indesit Company use to programme these PCB’s you would be advised to use your five year parts guarantee or try and source a refurbished module.
