2nd to night. was a 110 earlier.
Unplug, wait a minute, plug back in, should auto set to 12:00 if not timer faulty, some screws under the front panel, (On my 110 anyway,) probably same on 90, would be my start point to remove front, to get timer, espares.co.uk list them at £54.99 Other places might be cheaper, but espares do a price match, and they are helpful. NO I do not work for espares, just used them.
