Sime Friendly E boiler problem

[joeyd]

Since switching Sime Friendly E boiler over from winter to summer setting I am no longer getting any hot water. 'Demand' light doesn't come on when hot tap is opened. Pressure o.k. Is this an internal electrics fault?

Any help??

Thanks

Sounds likel a failed diverter valve.

In spite of the name these are not very friendly boilers.
