Customer Question
Hi I have recently...

Hi I have recently bought a house with a Servowarm Elite 21 Plus which was recently serviced and working ok. Since the service I have bled the radiators and now find that the boiler cuts out shortly after start up (usually 15 to 20 seconds after firing). When activated the boiler goes through its start up routine and the lights on the front panel light up all the way through to the 3 flames which I believe indicate it is running and heating. Within the following 10-15 seconds the boiler stops firing.

Contractor's Assistant: I'll do all I can to help. How long have you been dealing with this?

Just a couple of days, we have not moved in yet so not critical from a time point of view

Contractor's Assistant: Do you plan on doing the work yourself?

It depends what is required, I am not qualified to work on gas appliances but reasonably handy if there is something simple I can do

Contractor's Assistant: Anything else we should know to help you best?

The boiler is linked to a Siemens RCR10/433 controller with a Siemens RDH10RF room thermostat.

Have you refilled the system?
Servowarm systems are notorious for having no storage tank, it sometimes is as strange looming as a flowpot at high level in the corner of an upstairs room

Thanks. Having previously had a combi that needed topping up to maintain operating pressure I did look to see if there was an equivalent top up valve but could not see anything near the boiler. I will need to check to find the tank. What is the procedure for correctly topping up? Can you advise.
Plumber: Andrew Smith, Engineer replied 7 months ago
Many if these types don't even have a cold water feed and may need a watering can to get it filled.
Good luck.
Try and follow all copper pipework upwards.
