  George CareySep 8, 2025
  If your Warmhaus Boiler displays error E 37, it indicates a low voltage issue. The voltage is less than 165 VAC +/- 5% on the supply network during normal operation, OR less than 182 VAC +/- 5% during Au-TO calibration mode. Contact your electrical supply network provider. The error will clear if the supply voltage is greater than 170 VAC +/- 5%. If this failure is observed during calibration, calibration cannot be completed unless the supply voltage is greater than 188 VAC +/- 5%.

  If your Warmhaus Boiler shows error E 06, this indicates a gas supply failure. To resolve this: first, reset and restart the boiler. Check if the boiler's central heating valves are open; if closed, open them. Also, ensure that all radiator valves are open, with a minimum of 3 meters of radiator open. Reset the boiler again to see if the problem is resolved. If it continues, call an authorized service.

  If your Warmhaus Boiler displays error E 07, it indicates a lack of water in the system, pump blockage, pump failure, pump harness issue, or installation blockage. First, reset the boiler to see if the problem resolves. Check that the boiler's central heating valves are open; if they are closed, open them. Also, ensure all radiator valves are open, with a minimum of 3 meters of radiator open. Reset the boiler again and check. If the issue persists, call an authorized service.

  If your Warmhaus Boiler is showing error E 03, this indicates high water pressure in the boiler (greater than 2.8 bar). Initially, check the filling tap of the boiler and ensure it is closed. During boiler operation, the safety valve may continue to drain water, so ensure it's connected to a drain line. If your plumbing line has a drain cock, turn the boiler off and let the pressure drop to 1-1.5 bar, then switch it on again. If the pressure increase reoccurs, call an authorized service.

  If your Warmhaus Boiler displays error E 20, this indicates a lack of water in the system, pump blockage, pump failure, pump harness issue or installation blockage. Begin by resetting the boiler to check if the problem is resolved. Ensure the boiler's central heating valves are open; if closed, open them. Check that all radiator valves are open, with a minimum of 3 meters of radiator open. Reset the boiler again and check. If the issue persists, call an authorized service.

  If your Warmhaus Boiler displays error E 21, it indicates a lack of water in the system, pump blockage, pump failure, pump harness issue, or installation blockage. First, RESET boiler and check if problem removed. Check boiler central heating valves are open if they are closed open all. Check all radiator valves are open if they are closed. Minimum 3 meters of radiator must be open. RESET boiler and check if problem resolved. If the issue persists, call an authorized service.
