Any advice appreciated with the following problem:
I have a Glowworm Compact 75e (Gas Fired) that requires the Hot Water demand to be open to max before firing and requires CH to be off before it will fire up. The boiler is about 6 years old and has not been changed or serviced in this period. No changes to CH or DHW in this time. The problem has just started happening (returned from holiday ~ 1 week ago and could not get any hot water when CH was on).
The CH is working fine - Is this likely to be a service issue or a failure of the DHW switching?
Thanks
