Have problem with Baxi 130HE. DHW works fine, but when timer calls for CH it goes into anticycle (start is code 21, takes few seconds for diverter to move, then 26 displayed). The strange thing is if the DHW is running and the timer is calling for CH, then when the DHW stops the CH kicks in normally (after the normal CH shutoff it displays code 26 for a while - assume this is normal?)
Originally thought it may have been diverter valve , but changed to no effect, Has anyone seen this - Im going to put multimeter on flow switch (in case it is somehow sticking). The boiler had been drained and not in use for 6 months so took pump out to clean and inspect (bit of deposit, but looked not too bad)
Any ideas??
Cheers
