Timer non-operational?

Post  Baz on Sun Oct 27, 2013 4:48 am

Hi,

I've recently moved into a property fitted with a Boilermate SP A-Class. The problem seems to be that the heating will always come on, even outside of the timings on the machine. Even if I set the rocker to OFF for central heating, the heating will still fire up when the temperature drops below the set number on the hall thermostat.

I've taken the front cover off and can see that the CH light is constantly illuminated. When I flick it to off, it stays illuminated. Even if I flick the hot water switch from 'constant' to 'off', the CH and HW lights stay illuminated.

It's like the timer and rockers are completely ignored and everything is 'active' all the time. Any idea what's going on here?

It looks like I get error code c0/31 C0/31.

Hi Baz
The Error 31 is a external electrical error regarding your 240V/50Hz  power supply is not coming in with 50Hz. Without deeper testing your Boilermate SP (SP is for sealed Product, like the privies Systemate )there is no chance for a quick fix. This could be A: the installer has linked the selectors out, regards to a programmable Room stat or multi zone system, or yours is a non clock model, where the 2 canal programmer is fitted or B: your PCB is faulty. This problem would be more than a DIY job. I would recommend to get a Gledhill specialist in, to do a diagnostic check to find out. Do not go to your local Plumber or Boiler chap, unless he is specialised in Gledhill Products, or you ending up, paying money for head scratching. The electric on the A class is a bit complex.
( I hate this b...y clock change, my body clock is still on summer time lol)

Hi Mario,

Thanks for the detailed response. Much appreciated. I will follow your advice and get a Gledhill engineer out to take a look.

Do you think the 31 error is related to the timer/switches not working, or is this likely to be a separate problem on top of my 31 error?

Thanks.

Hi Baz
sorry for the late replay, but I also have a day business to earn my living.
Your Error 31 is related to an external electric fault. This can also be coursed from a bad whether power dim or so, also could be an old error. The PCB is storing any fault ever happens up to ( if I am correct) 17 events, before it drops the first one. So, i would ignore this for now. This error is so rear, i came across this only once or twice, on over 12000 units, i have repaired over the years.This has nothing to do with your timer problem and is something completely separate and an external fault on your electric supply to the Gledhill boiler.
kind regards     Master Mario
