CAN ANYONE HELP ME. I DONT KNOW WHAT MODEL BOILERMATE I HAVE BUT HOUSE WAS BUILD IN 1993/94. BOILER PUMP (BLUE LOWER ONE) IS RUNNING ALL THE TIME COSTING ME IN ELEC AND GAS. THE STAT IS ALLWAYS CLOSED WHEN I TESTED IT SO I THOUGHT THIS WAS THE PROBLEM BUT WHEN I TOOK THIS OUT OF THE CIRCUIT PUMP STILL RUNS SO COULD IT BE BOTH STAT AND PCB BOARD WITH TIMER DELAY ON THAT ARE U/S? ALSO NEON INDICATOR DOES NOT WORK. HAS ANYONE HAD ANY SIMILAR PROBLEMS?
GLEDHILL BOILER PUMP RUNNING 24/7!!!

Hi. I have tried turn stat between winter and summer but does not make any difference not does it effect Ohm reading when i put a multimeter on it and turn stat. Reading is allways o.1 Ohms.
Over 1 hour ago i disconnect stat from terminal 7 and just a minute ago boiler pump has cut out for the 1st time in months! But if delay timer is ok is should cut out in 4-6 mins?
My Paper work just says Boilermate, not boilermate II or anything so maybe its the 1st one?

Sorry it is in fact a Boilermate II. I have just seen it on the panel i have taken off!

What setting is the thermostat set on the boiler at??
Which one of the two pumps is running all the time??
Which one of the two pumps is running all the time??
the boiler is set on Max. Its the boiler pump that is running all the time, the one that that says primary return to heat generator. Its not the red ratiator pump. just turned power back on and now have buzzing noise from bottom pcb
bottom one is the pump delay timer
Do you think it could be the stat and the timer delay causing pump to run 24/7? why did pump take and hour to cut out after i disconected stat?
i opt for the delay timer pcb.
But why is stat constantly closed? On drawing it shows it being normally open. When temp drops stats closes putting a supply onto delay pcb and thus also bringing in motor for pump.
When stat opens when sufficient temp is reached delay timer should start and pump should cut off within 4-6 mins! So i am led to believe......

cause the thermal store is up to temp and the pump is circulating very hot water perhaps??
If it was up to temp the stat would be open. It should only close when tempature drops, thus energising pcb board and time delay and inturn energising boiler pump. once up to temp stat will open and pump should cut out within 4-6 mins.......
What boiler do you have?
If the boiler has a thermally controlled pump overrun, the boiler stat set at max and the store is hot then the pump will continue to run until it cools sufficiently.
Failing that as previously said change pump board and try that

it says PRIMA B on it!
Like i say according to drawing the timer delay should cut pump out! Its costing me loads on gas and elec as boiler keeps firing up with the pump running all the time!
