Changed the batteries in timer/thermostat but the boiler is still not talking to the transmitter heating still on can you help??


Is this a wireless system, meaning no wires between the thermostat and the boiler? If so, check to see if the code buttons have been reset. If this is a hardwire system, the relay on your control board may be stuck. In any case, you can always shut off the boiler by turning off the gas and/or circuit breakers.

Boiler won't ignite for hot water unless heating is on.


If this is in a RV the propane monitoring valve may require more gas flow to turn on than the water heater requires. A central heating system requires substantial gas flow so when the monitoring valve opens to fire the central heating, there is enough gas flow to also fire the water heater.

Cointra godesia water heater... works perfectly but only for 5 mins then pilot goes out... u can relight straight away and it works for 5 mins again .. this boiler I have just bought new ... j


In my experience thermocouple either work or they do not.when a water heater runs for a length of time before the interupter cuts the pilot or on some modules safety cut out sensor also known as over heat thermostat cuts the gas supply the problem can normally be found in the flue restricting the disposal of waste products of the combustion or the lach of air flow through the appliance

My boiler will not fire up the pilot light is on, the thermostat clicks when asking for heat but boiler will not go on. What could be the problem ?


Best case, the gas selector switch is set to the pilot position. Rotate it to the full open position to allow the boiler to fire. If it is already in the normal operating position, you will probably need to replace the gas valve.

This is a cold boiler problem.
There are several reasons for a cold boiler...boiler element is open, no power to the boiler element, thermostat is not functioning properly, or it could even be a board problem not delivering voltage to the boiler.
First start by opening the top and reseating all connectors on the board, if this does not help then you will have to extract the insides of the machine from the case to get at any of the boiler and thermostat hardware.
Start by removing the 1 screw holding the inside workings to the outer case. This is located on the right top side of the machine beside the grinder.
Use great caution while pulling the guts out of the case and watch the dredge drawer switch does not hang-up on the case. Snake the power cord through the bottom of the case while pulling the inner workings out of the case.
There are 2 elements in the boiler check them both for a resistance (they will not be the same resistance) if either are open then then replace the boiler. Check the thermostat on the back of the boiler for resistance, if open or shorted, then replace. Check thermal breaker on boiler, this should be shorted if not, reset it by pressing the button in the center of the breaker.
If none of this works then you will have to depress dredge drawer switch front door switch and insert the brew group to depress the brew group switch, plug in the unit and turn it on.
Check for voltage on the elements on the boiler.
If no voltage then check all connections.
If you have gotten this far there is a good chance it is the board fault and it will need to be replaced.
Be shure to label all connections to the mother board as there are several connectors that can be placed in the wrong position while reassembling.
NOTE: This depth of trouble shooting should only be attemted if you are completely comfortable with electrical/electronic repair.
