A restaurant in Solihull had a Potterton Gold Combi 28 HE A showing E161, a fan fault. We replaced the fan and got the boiler working. Testing then showed the PCB was intermittently dropping the voltage to the pump, so we picked up a new PCB and fitted it the same day. The heating and hot water were working before opening time.
A restaurant in Solihull called us out to its Potterton Gold Combi 28 HE A, which was showing E161, a fan fault. We replaced the fan and got the boiler working. We then tested it and found the PCB, the boiler's main control board, was intermittently dropping the voltage to the pump. We picked up a new PCB and fitted it the same day. The restaurant owner was extremely happy: they had heating and hot water working again before opening time.

A restaurant in Solihull called us out to its Potterton Gold Combi 28 HE A. The boiler was showing E161, a fan fault, and wouldn't run, so there was no heating or hot water. The first photo is the boiler when we arrived.
We replaced the fan and got the boiler working again. The third photo shows the old fan and the new one side by side.
With the boiler running, we tested it and found the PCB, the boiler's main control board, was intermittently dropping the voltage to the pump. We picked up a new PCB and fitted it the same day. Our Potterton boiler repair page covers other Potterton faults.
The restaurant owner was extremely happy: with both parts fitted, the heating and hot water were working again before opening time.
It is a fan fault: the boiler cannot run its fan properly, so it will not light. A failed fan is a common cause, as here, but wiring or the control board can cause it too, so it needs an engineer to test.
Once the new fan was in and the boiler was working, we tested it and found the PCB, the main control board, was intermittently dropping the voltage to the pump. Left like that, the boiler would have kept cutting out, so we picked up a new PCB and fitted it the same day.
No. A reset clears the display, not the fault. If a code keeps coming back, stop resetting it and call an engineer with the code and the boiler model. If you can smell gas, call the National Gas Emergency Service on 0800 111 999 first.
No. It needed two parts, the fan and the PCB, both fitted on the same day, and the restaurant had heating and hot water before opening time.

The pressure kept rising even with the boiler off. We found a pinholed plate heat exchanger and replaced it, with the pressure relief valve, from the van. No new boiler needed.
Read the case studyCalled at 8.30pm with fault C7. We fitted a new fan, then traced an H09 code the customer had been resetting for months to the PCB and replaced that too, with genuine Worcester Bosch parts.
Read the case studyThe right-hand manifold inside a Worcester Greenstar 28i Junior was leaking. We diagnosed it, tracked the part down locally, fetched it and fitted it the same day. Customer extremely happy.
