I have the above oven with an er7 showing after cooking for 10-30 mins.customer says that it errors quicker the higher the temperature is set.
hava looked on the fault codes and can see for the Hotpoint ovens that this can be a control pcb fault but just wanted to check this was correct for this model before I go out and check and tighten connections.
ER07 Too hot on the main board
1. Tangential fan
2. Correct oven installation in the kitchen (air flow)
3. Correct positioning of thermic insulation / venting
4. Main board
