Common problems with wall mounted boilers

Problem phenomenon: The water pump does not operate, the controller alarms, and the problem code displayed on the screen is insufficient pressure.

a) The pipeline is short of water, and the pressure gauge shows insufficient water pressure in the pipeline.

a) Supplement water for pipeline water shortage; If the pipeline leaks, find a way to seal it.

b) Test with a multimeter, if the heavy pressure switch is not connected, replace the heavy pressure switch; If the contact is not good, reconnect it; If the circuit is broken, replace the wires; If the wrong terminal is plugged in, connect it correctly.

Problem phenomenon: The water pump does not operate, the fan does not operate, the controller alarms, and the problem code displayed on the screen is pipeline water shortage.

a) Use a multimeter to test whether the output power supply of the water pump is normal and whether the contact is good. If there is no voltage output from the controller, it is a controller problem, replace the controller; If the controller has voltage output and the water pump is out of power, it is due to the connector falling off, poor contact, or wire disconnection; If it falls, make good contact again. If it doesn't make good contact, make good contact. If the wire is disconnected, replace it.

b) If there is voltage input to the water pump but the pump does not rotate, it may be due to the pump being locked. Loosen the flat screw on the water pump, use a flat screwdriver to turn the water pump shaft, and make the water pump rotor rotate to restore normal operation; If the water pump is not locked and a multimeter is used to test for open or short circuits, it indicates that the water pump is burnt out and needs to be replaced.

② Problem phenomenon: The water pump is running, the fan is not running, the controller alarms, and the display screen shows a missing problem code for the pipeline.

How to replace the wall mounted boiler battery

1. Wall mounted boilers do not require battery replacement as they are powered by alternating current. But the temperature controller of the wall mounted boiler needs to replace the battery. The battery is located behind the temperature controller and needs to be removed from the wall with a flat screwdriver. Then, open the back cover and replace the old battery with a new one.

2. Wall mounted boiler is a popular heating device in recent years, as its usage and effectiveness are far better than other heating devices, so it is very popular in the market.
