Problem: "On the new boiler BOSCH WBN 6000-24C an EA error appears - the flame is not detected. The more degrees are exhibited, the less the error. But at low temperatures, it gives an error almost every day. Before the error occurs, the flame icon disappears. What to do?"

Check whether the protective wire is connected;
Make sure whether the gas crane opened;
Check the gas pressure, correct if necessary;
Make sure that the electrical connection is properly connected;
Check electrodes with wires, replace if necessary;
Check output system flue gases, clean or repaired if necessary;
Check the gas adjustment, if necessary, fix;
For natural gas: Check gas flow control relay. Replace if necessary;
When working with the air fence for burning out of the room, you should check the air supply to the room and the ventilation holes;
Clear heat exchanger;
Check the gas fittings, replace if necessary.

In 90% of cases, the problem is in the board. The best just contact the service center. There will be able to provide high-quality assistance: make diagnostics and repair the boiler.

Check the boiler sensor and connection wires.

C1 error code - fan rotates low frequency

Check the voltage on the network.
Check the flue gases. If required, make cleaning or repair.

C4 error code - no discovery of a differential pressure switch when not working fan

Verify DIF. pressure switch.

The C6 error code - does not circuit a differential pressure relay

Check DIF. Pressure relay, as well as flue gases.

C7 error code - does not function fan

Check the fan, wire and plug. If required, replace.

CE error code - small pressure for filling the heating system

Water topping.

D7 error code - there is a malfunction of the Gas fittings of the BOSH 6000 wall boiler

Check the connection wire.

Error code E2 - malfunction or breaking temperature sensor on the feed line

Check the sensor for the presence of a defect, as well as a possible short circuit of its wire. If required, replace.

Error code E9 - heat exchanger temperature limiter

Check the heat exchanger temperature limiter for the presence of a defect, as well as a possible short circuit of its wire. If required, replace.
Check the operating pressure in the heating system.
Check the temperature limiter if necessary, replace it.
Check the pump start. If required, replace the pump.
