What does error code W.3 mean on a Thermor heat pump water heater?

Error W.3 indicates the water temperature probe is defective or reading outside acceptable parameters, typically showing an abnormal 85°C reading. Check all sensor connections and ensure proper positioning. Verify the ohmic value of the probe. If everything appears normal, the temperature sensor needs to be replaced by a qualified engineer.

What does error code Err 01 mean on a Thermor electric water heater?

Error Err 01 on Thermor Duralis models indicates the battery powering the ACI Hybrid anti-corrosion circuit is no longer effective. Wait for 2 complete off-peak heating cycles (approximately 16 hours) for the battery to fully charge. If the error persists, the thermostat assembly may need replacement.

What does error code Err02 mean on a Thermor towel rail?

Error Err02 on Thermor towel rails indicates the digital control or thermostat has overheated. Allow the towel rail to cool down completely before restarting. Ensure towels are not covering the control panel or blocking ventilation.

What does error code W.30.4 mean on a Thermor heat pump water heater?

Error W.30.4 indicates the water and/or evaporation temperature is outside the compressor's acceptable operating range. This causes the heat pump to stop and may activate electric backup heating. A qualified engineer should check the ducting and insulation of the system.

What does error code W.50.3 mean on a Thermor Aeromax Split heat pump water heater?

Error W.50.3 indicates a communication error between the outdoor unit and the interface card. Check that the outdoor unit receives proper electrical power. A qualified engineer should inspect interconnection wire 3 and test the coil circuit, relay, and high-pressure switch on the external unit.

What is the pilot wire on Thermor electric radiators?

The pilot wire (fil pilote) allows centralised control of multiple radiators from a single programmer or energy manager. It transmits operating commands including Comfort, Eco, Frost Protection, and Off modes. All radiators with pilot wire capability follow the same protocol, enabling whole-home heating management from one controller.

How do I maintain my Thermor heat pump water heater?

Thermor recommends three essential maintenance steps: operate the pressure relief valve monthly to prevent jamming from scale deposits, drain the tank at least every two years in hard water areas to remove mineral buildup from the heating element, and inspect electrical connections and thermostats for proper functioning.

Why is my Thermor towel rail not heating up?

First check the thermostat is set to the desired temperature and functioning correctly. For electric models, check the fuse in the wall switch. If the controller appears to work but no heat is produced, the heating element may have failed.

How do I clean the condensate drain on my heat pump water heater?

Clean the condensate drain tube annually to prevent blockages. Use compressed air to blow through the tube, insert a small cloth attached to something rigid to clear debris, or use a small bottle brush. A blocked drain can cause water to back up into the unit and affect performance.
