What to do if my Warmhaus EWA 28 Boiler has no ignition?
If your Warmhaus Boiler fails to ignite, the issue might stem from a gas supply failure. First, try resetting the boiler. If that doesn't work, check that the boiler's central heating valves are open, and ensure all radiator valves are open (at least 3 meters worth). If the problem persists after resetting again, it's best to call for authorized service.
What to do if the safety thermostat intervention occurs in my Warmhaus Boiler?
If the safety thermostat in your Warmhaus Boiler is intervening, it could be due to a lack of water in the system, a pump blockage or failure, issues with the pump harness, or a blockage in the installation. To address this, start by resetting the boiler. Then, check that the boiler's central heating valves are open, and ensure that all radiator valves are open (covering at least 3 meters). If resetting doesn't resolve the issue, contact an authorized service for assistance.
What to do if there is no water circulation in the Warmhaus Boiler system?
If there's no water circulation in your Warmhaus Boiler system, it could be due to several reasons: lack of water, pump blockage or failure, pump harness issues, or installation blockage. First, try resetting the boiler. Next, check that the boiler's central heating valves are open and that all radiator valves are also open (ensure a minimum of 3 meters of radiator is open). If the problem continues after resetting, contact an authorized service.
How to fix low water pressure in my Warmhaus EWA 28 Boiler?
If you're experiencing low water pressure in your Warmhaus Boiler system, it might be due to insufficient water pressure in the boiler itself. You should fill the boiler to a pressure of 1.2-1.5 bar, as indicated on page 28 or 29 of the manual. Also, verify the system pressure is within 1.2 - 1.5 bar using the manometer located at the bottom right of the boiler. If the issue continues, contact an authorized service and then reset the boiler.
What to do if there is high water pressure in my Warmhaus Boiler?
If the water pressure in your Warmhaus Boiler is too high (over 2.8 bar), first, call for authorized service. Then, carefully inspect for intermittent or open contacts on the harness. Check the domestic heating water temperature sensor resistance according to page 95 at section 4.30; if it's out of tolerance, replace the NTC. Also, check the cabling and connectors between the double NTC and the board. Finally, reset and restart the boiler.
What to do if the central heating FLOW temperature sensor is faulty in my Warmhaus Boiler?
If the central heating FLOW temperature sensor in your Warmhaus Boiler is faulty, first reset the boiler to see if the problem clears. Check if other gas devices are working correctly. Ensure the main gas supply valve and the boiler gas supply valve below the boiler are both open. If the issue remains after these steps, contact an authorized service.
What to do if the exhaust (FLUE) temperature probe is faulty on my Warmhaus EWA 28?
If you encounter a fault with the exhaust (FLUE) temperature probe on your Warmhaus Boiler, first try resetting and restarting the boiler. If the problem persists, contact an authorized service for assistance.
What causes the exhaust thermostat to intervene in my Warmhaus EWA 28 Boiler (Open Combustion Chamber)?
If the exhaust thermostat intervenes in your Warmhaus Boiler (Open Combustion Chamber model), it could be due to a faulty flue sensor. First, try resetting and restarting the boiler. If the problem continues, contact an authorized service.
What to do if the DHW temperature probe is faulty in storage tank mode on my Warmhaus EWA 28 Boiler?
If you're experiencing a fault with the DHW (Domestic Hot Water) temperature probe in storage tank mode on your Warmhaus Boiler, first contact an authorized service. Then, check for intermittent or open contacts on the harness. Check the domestic heating water temperature sensor resistance, cabling, and connectors between the NTC and the board. Finally, reset and restart the boiler.
What causes the gas valve modulator to disconnect in my Warmhaus Boiler?
If the gas valve modulator is disconnected in your Warmhaus Boiler, it could be due to the gas valve harness. First, contact an authorized service. Also, check the gas valve cabling between the board and the gas valve.
