Fault code history can be accessed:
SETTINGS/SERVICE/GAS HEATER 01/7378 CONT/FAULT LOG
YouTube Video - MagIQtouch Heater Fault Log
If all burners DO NOT light and the flame does not touch the flame sensor and gas pressures have been confirmed as correct
- Check flames travel freely across all burners at ignition
- Check burner slots are aligned
- Check cross-lighting slots on burners for obstructions - clean/clear is required
To assist in the field with issues of intermittent fault code 7 and 11, we have introduced 2 x new kits
that replaces both sparker and sensor probes
Kit Pt# 651799 - replaces sparker and sensor in condensing heaters (PVC flues and drains)
Kit Pt# 651800 - replaces sparker and sensor in non-condensing heaters (metal flues and no drains)
