I took one more look before calling anybody. I disconnected the motor from the three way valve and manually operated the valve. I checked the motor is working by switching boiler off and on. All seemed ok so refitted motor. CH now works OK. Probably a sticky valve or the motor may have been...

Well Beerlover I think you are right. I cannot see the spindle move and the sound when switched on/off seems to come from that motor so something must be sticking. I'll call GlowWorm warranty people and see what I acn get them to do. Thanks very much for your help. Spot on. Cheers

I just read your reply after I sent the last text. Cheers

I cannot hear anything apart from what sounds like the ignition. I've looked carefully and cant find anything thats moving or anything that looks like it would move. Where is the motor your talking about? I can see the main pump but no access to view any of the moving parts. Cheers

Hi again Beerlover, I have turned up the temp settings for both CH and DHW, now i see the d23 is in winter mode. But still the only water being heated is what is in the boiler. I have the cover off but cant see any moving parts yet. I'll get a torch :-) Cheers

I still have the problem. It may just be the summer/winter mode settings as I've just read another document that says the CH is disabled when in summer mode. Does anybody know how to change d23? Cheers.

I have found in fault memory that there has been error 22. Somethin about low water presures or air in system. What would be the best way to purge the system, mayeb the pump needs bleeding or something.. Cheers.

Is there a different password or code so I can change the summer/winter mode? Cheer

I've jsut checked the system when hot water running. I guess the pump is pumping around the internal system heating the DHW water system pipes. d99 shows 16 when hot water tap on.

Yes I have both the tap and rad displayed.

I tried again to fire CH. Boiler fires as before and just heats the water in boiler. I checked d99 now it shows '7' pump overrun. I'm guessing there is a valve somewhere but shouldn't the bypass valve open if there was pressure? Hmmm I'm thinking the pump rotors have bust as the pump is running...

d99 shows 31. Book tells me that that is related to summer mode. I have no external controls attached to this boiler. DHW works fine. I tried to chage d23 to winter mode but it wont let me change it. Cheers.

Thanks for replying Beerlover. I have tried to access the extra codes via d99 but nothing happens. When d99 displayed I press 'mode' and expected to be able to view a further list but nothing happens. I'll go and try again. Maybe I'm doing something wrong. Cheers.

Hi, I have a Ultracom 30cxi which has been installed for around 2 years now. I recently tried to switch on the CH now that the cold weather has arrived but it didn't come on. What I found is that the system is heating the water in the boiler, the pump sounds like it is on but no water is being...
