Warmhaus Combi Boiler Error Codes Warmhaus has an extremely powerful range of boilers that are extremely reliable and normally won’t let you down. Sometimes things can go wrong, so we’ve created the handy Warmhaus error codes chart below at a glance.
Warmhaus Boiler Error Code Solutions
Enerwa and Priwa Error Codes | |
| Fault Code | Possible Cause |
| rE 02 | Low water pressure in heating system – parameter is adjusted wrong |
| E 03 | High water pressure due to excessive water pressure or safety valve error |
| E 04 | Domestic hot water (DHW) temperature sensor failure – possible error with electronic card or the NTC sensor. |
| E 05 | Temperature sensor from radiator error – electronic card detecting a failure. |
| E 13 | Exhaust gas temperature sensor error – excessive temperature alarm. |
| E 14 | Exhaust gas temperature sensor error – electronic card detecting an anomaly in the gas exhaust gas sensor. |
| E 15 | Fan error – a fan being blocked or excessive external air pressure. |
| rE 06 / rE 08 | No ignition – control gas supply line valves could be open |
| rE 07 | Safety thermostat intervention from dual sensor – excessive heating occurring due to any failure during normal operation, try resetting the boiler. |
| E 10 | AUX output sensor error |
| E 16 | AUX return sensor failure |
| E 11 | Gas valve modulator connection is broken – could be due to an internal failure. |
| E 17 / E 19 | Maximum difference failure between 2 NTC temperature sensor – poor circulation. |
| rE 28 | Maximum locking number reached – boiler has reached the maximum reset number (5 times in an hour) – attempt 1 reset each hour thereafter. |
| E 37 | Low voltage error – voltage required for operation is too low. |
| E 40 | Electricity network frequency error – fluctuation in electricity frequency. |
| rE 41 | Flame loss after 6 successive ignitions – gas supply line valve being open. |
| E 42 | Error with pushbutton |
| E 43 | Room thermostat communication error – disconnection or communication loss in room thermostat. |
| rE 44 | Gas valve error due to opening period without flame – try resetting the boiler. |
| E 62 | Calibration request – boiler has detected an absence of calibration control. |
| rE 72 | Delta T error – boiler failing to ignite. Could be due to a gas line valve being closed or a flue error. |
| E 74 | Temperature sensor error. |
| E 77 | Current values reached – check combustion values and CO2 calibration, try resetting the boiler if this fails. Either the board or the valve will need replacing. |
| E 78 | Regulation current value has been reached. Try resetting the boiler, check the gas pressure and check the combustion values and CO2 calibration – if this doesn’t work the board or valve needs replacing. |
| E 79 | Minimum regulation current reached – try resetting the boiler – checking the gas pressure and checking the combustion values and CO2 calibration – the board or valve might need replacing. |
| rE 80 | Gas valve driver error – due to an internal failure. |
| rE 81 | Ignition problem at the first start – this could be due the flue line, possible flue blockage or chimney gasket. |
| rE 82 | Burning problem – due to the flue line either being blocked or chimney gasket. |
| E 83 | Temporary mis-burning error – could be due to a gas pressure or flue line issue. |
| E 84 | Capacity reduction for detected low gas inlet pressure – check the CO2 calibration values. |
| rE 88 | Error in gas line cycle – possible gas valve component error. |
| E 89 | Problem on combustion feedback signal – gas pressure needs checking. |
| E 90 | Error in regulating combustion – possible error with the calibration values chimney gas valve and board. |
| E 92 | Air compensation active – the CO2 values need checking, possible error with the wind presence. |
| E 93 | Unable to regulate combustion – possible calibration value issue, chimney gas valve or board. |
| E 94 | Low gas pressure or exhaust recirculation that could be an issue with gas pressure. |
| E 95 | Intermittent combustion value caused by a possible error with electrode position or electrical connection stability. |
| E 96 | Flue blockage – due to chimney and combustion values – the boiler may need a calibration. |
| rE 80 | Gas valve error – possible internal error. |
| rE 81 | Ignition problem at the first start – could be due to a problem with a flue line. |
| rE 82 | Burning problem error – flue line error. |
| E 83 | Temporary mis-burning error that may be caused by the gas pressure or flue line. |
| rE 88 | Gas line cycle error – could be due to a gas valve component error. |
| rE 98 | Electronic card start error. |
| rE 99 | An error has been detected in the Combi, try resetting the boiler. |
