NO HOT WATER . RADIATORS HOT

[DTPEARSON]

Hi just got in from work.
CH programme is turned off due to mild weather. Hot water is programmed on.
Radiators hot. Water is cold.

Boiler is Worcester Bosch oil heatslave 20/25.
Installed 2 years no previous problems.

Any ideas would be welcomed.
Thanks DTP

Would suspect the flow switch. Fog 23 in the manual.

read manual but did not know how to make pump run on without firing boiler up.
Held diverter lever half way up and pressed it in. it would not stay in possition unless held.
fired up and all seeems to be well now.

Thanks for suggestions
