Boilermate 2000 ACB boiler pump supply constantly ON

Post  Weeguy on Sun Jul 23, 2017 2:00 am

Hi,

My Boilermate 2000 ACB dated 2003 recently died (processor not starting and all outputs on).
Purchased a new one (dated 2016 and software version same) from eBay and now fitted.

Problem I have is the boiler pump has a constant 230v supply even when the output is off, so boiler pump is running constantly. No error codes and ACB completes diagnostic with jumper 5 fitted.

Confident in my soldering skills if anyone can point me in the right area.

Appreciate I should have went to CTD but lesson learned.

Thanks.

Boilermate pump running

Post  HizerKite on Wed Aug 09, 2017 1:16 pm

Hi, did you ever find an answer to this?  My boilermate sometimes keeps the boiler pump on for hours after it's topped up the thermal store - running a hot tap for a few seconds cures it - the pump goes off a couple of minutes later - can't work out the cause so curious about yours

Regards
Richard

Hi. Think my problem is being caused by a faulty solid state relay or varistor.
Have been assured acb i purchased was new.
Anyway have resurrected old acb(faulty processor) by replacing the five capacitors.
