How to Fix / Troubleshooting
Safety first: Disconnect power before any internal inspection.
User-level checks:
- Reset the microwave by unplugging for 10 minutes, then retry different modes (microwave-only, grill-only, convection-only if available).
- If only certain modes trigger E15, note which ones for the technician.
Technician-level checks:
- Inspect the control PCB for relay damage (burn marks, melted casing).
- Test the affected relays for proper operation and coil resistance.
- Check the loads (grill element, convection heater, fan) for shorts that may be overloading the relay.
- Replace the control PCB or individual relays as per Hoover service procedures.
Recommendation: Because this involves mains-voltage switching, relay and board work should be done by a professional.
