It seems that a common error code on some older Indesit washing machines is error code 7. This code can show itself as F07. Some models don’t have a digital display though. So washing machines that have a rotating control dial will instead flash the door lock light in cycles of 7 flashes. As Indesit and Hotpoint are made by the same company some Hotpoint models also use this error code (WF and WD models).
This error code usually means, “heater relay stuck”. The heating element is switched on via a relay. The relay is built into the main PCB. This relay is known to get jammed, causing error code 7. In my experience this has usually meant a new PCB needed fitting. But as the PCB replacement comes without the main processor (EEPROM chip) one of those is also needed.
So this repair is likely to be expensive. I have heard anecdotally of engineers freeing off the jammed relay on the PCB by giving it a firm tap. However, if it’s stuck once there would be a chance the relay could get stuck again later on.
If a washing machine is still under the five-year parts warranty it would be cheaper to let the manufacture fit these parts. Many white goods manufacturers now operate fixed price repairs schemes.
