Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|
N/A | Water is not heating. Possible Cause: No operating voltage. | Restore the power supply. | DIY Safe |
N/A | Water is not heating. Possible Cause: Operation without water; the overheating safety switch has shut off the heater. | Switch off the appliance, wait 10 minutes, fill the water system, and switch the appliance back on. | DIY Safe |
N/A | Extremely long heating time. Possible Cause: Water tank is scaled up. | Descale the water system (see maintenance instructions). | DIY Safe |
N/A | Water runs away – boiler cannot be filled. Possible Cause: Safety/drain valve is open. | Close the safety/drain valve. | DIY Safe |
N/A | Boiler cannot be drained even though the safety/drain valve is open. Possible Cause: The drainage outlet of the safety/drain valve is blocked. | Check the opening for any debris (such as slush, ice, or leaves) and clean the opening if necessary. | DIY Safe |
N/A | Boiler cannot be drained even though the safety/drain valve is open. Possible Cause: The ventilation hose is blocked. | Check the hose opening (refer to the upper section). | DIY Safe |
N/A | Water is dripping from the drainage outlet of the safety/drain valve. Possible Cause: The elbow fitting on the boiler is bent. | Check the hose for any kinks and straighten the hose. | DIY Safe |
N/A | Water is dripping from the drainage outlet of the safety/drain valve. Possible Cause: Water pressure is too high. | Check the pump pressure (max. 2.8 bar). When connecting to a central water supply (country or city connection), a pressure reducer must be used to prevent pressures above 2.8 bar from developing in the boiler. If these steps do not resolve the fault, contact an authorised service agent. | DIY Check / Tech Fallback |
