So getting the van ready and of course every dam thing is going wrong sorted most but this one

I have a fault code which cannot get rid of, W 45 H

The handbook for the boiler says
# 45 Only Truma Combi eco plus or Truma Combi comfort plus models.
No 120 VAC supply voltage. Restore 120 VAC supply voltage.
Overheating protection has responded. Contact Truma Service.

Not to worry it is a UK 240v but could only find US handbook.

In my handbook it also says there is a reset button for overheating protection but it is not there.
It is booked in for annual service in May but someone may have an idea
Ta folks

Well I just could not it alone could I
Fault found 240v inline 13a fuse was the problem, dont know why it showed good when tested but I changed anyway and boiler then worked fine.
Engineer will check it over when booked in for a service next month.
