Hi, I wonder if anybody could help me please, My Worcester 28 SI II will cut out after filling half a bath, then the red light flashes, after resetting it just trips again straight away and again and again.Same happens with central heating, it will run for 20 mins then cut out and wont reset.However here is the weird bit, if I then leave it for 40 mins or so to cool down it will again fill half a bath or will heat house for 20 mins.Its 9 years old and had a new pcb 6 years ago, this does sound to me like a dry joint again on the pcb or even a diode or capacitor that expands when the pcb gets hot. But im not the expert you are. I don’t want to replace the pcb and find out its just the same. Any ideas please??Thanks all in advance.
Pcb's don't reset automatically when they sense an internal failure. I would have to know how many times it flashes per second to give more advice. Here is the manual, go to pages 34 thru 41 for troubleshooting. Boilers can be very dangerous when not repaired properly, so use your best judgement. www.worcester-bosch .uk/install...
