Possible Causes
Open circuit on switched live output, Disconnected boiler/valve wiring, Failed output sensing circuit on receiver PCB, Blown internal fuse or track
How to Fix / Troubleshooting
Safety first: This involves mains voltage. Isolate power at the consumer unit and verify before opening the receiver or wiring centre.
- Check wiring centre: Inspect connections from the Drayton receiver (e.g. Heat HubR, SCR) to the boiler or zone valve. Tighten any loose terminals and repair damaged cables.
- Continuity test: With power off, test continuity from the receiver's switched live terminal to the boiler/valve input. An open circuit indicates a wiring break.
- Inspect receiver PCB: Look for blown tracks or internal fuses on the receiver. These are often not user-replaceable.
- Replace receiver if needed: If wiring is sound but E13 persists and the output does not energise under demand, replace the Drayton receiver or Heat HubR.
