robinson willey warmplan xx auto fails to ignite?

The flue fan has to run to vacate the combustion chamber. If that doesn’t happen during the purge period, the gas valves don’t open. Nothing to do with spark electrodes or sensors. Unwire the flue fan and put 240v direct across wires. If it runs, it’s a faulty pcb relay. If it doesn’t run, it’s a failed flue fan.

Hi we are looking for a Flame sensor/electrode for a Robinson Willey Warmplan XX part no SP820046. Can any one help?

Hi Richard thanks for your response to the problem with my heater. I would be grateful of any imformation regarding my problem. Alan

Hello

The problem I think is the flame detection thermocouple. It needs to send a current to the board and the current depends on the heat at the tip in the flame. This thermocouple is now shorter than it used to be and it takes several ignitions to deliver a sufficient current.

We had the same problem about a year ago. I suspected the control board but it wasn't. As I recall, it turned out that it was actually a failing solenoid coil on the gas valve. You could see the flame was not strong enough to keep the flame detector satisfied. If this is still of interest I could try to confirm my recollection. I need to take the cover off soon to try quieten the convector fan (again!!).

Hi i wonder if you can help me, My heater is about 3 years old & it has a fault that when it lights up it then turns off again this happens about 3 to 4 times after that it fine. I have noticed that a relay on the circuit board on the left sparks each time it lights & turns off i wonder if the relay is weak! I have looked for the board online & it is £164 + vat & before i order it i thought i would seek advice as it is a lot of money! thanks

Hi armoured-smiler
Have you still got you control board as mine is suspect at not sparking,

If it is the soleniod I have a 'used' gas soleniod (since they don't seem to sell them seperately), infact I here removed by my plumber a complete Warmplan XX (after fitting CH) and I am willing to sell off the bits as it's seems they might be wanted items.

Mine has been condemned because the gas valve is leaking. Anyone know if spares are still available?

Try cleaning the insulators on the spark and flame detector electrodes - lefthand side under cover plate.

Need a new solenoid for our Warmplan XX. Been in touch with Robinson Willey, they tell me the part is no longer available, even though the heater is still available. Have searched web, but no success. Can anyone suggest a supplier for spares valves?

There is a viewing eye-hole on the right hand side of the heater casing. If you look into it whilst the heater is starting up, can you see a flame at all? It should at least try to fire up, & you should hear the ignition ticking away. If it fires up, it's obviously not the solenoid gas valves that's the problem. It'll be the ignition probe or flame failure detection probe(s). I have the same pronblem with mine. the trouble is calling british Gas in is only any good if the guy they send to look at it really knows about these units, otherwise you could end up with all sorts of parts changed before you get to the bottom of the problem. However, this will still be cheaper than replacing the whole unit. They're great heaters though, and very economical. Well ahead of their time for economic heating use.

gas valve solenoid coil faulty (there are two coils).

it sounds like the twin solinoid on the gas valve

I cannot help I'm afraid but I have exactly the same problem. Considering a new one unless a simple repair can be carried out.
Are spare parts still available.
Would love to know if your heater was ever sorted.
