How do I reset the overheat stat on my Worcester 9.24 Electronic BF Combi Boiler?
As you said in your question Worcester Bosch have told you there is no reset on this boiler, its self resetting. If it wont reset then it needs a replacement part and I think you may be lucky and still be able to get them. There is nothing you as a non qualified person can do with this appliance so you will have to bite the bullet and get professional help .This part is an appliance safety feature and requires a registered installer to fit it and check the boiler for safe operation.
