What it is
The Potterton 720849801 is a wiring harness for the 3-way valve, pump and gas circuits on Potterton Apollo series gas boilers. It carries the electrical connections between the appliance control and these components, so a damaged or intermittent harness affects valve movement, pump operation and the gas side of the firing sequence together.
Signs this part needs replacing
- The 3-way valve fails to move between heating and hot water positions
- The pump runs intermittently or not at all despite a demand
- The boiler fails to fire or drops out during a demand for heat or hot water
- Fault indications relating to the pump, valve or gas circuits
- Visible damage, scorching or loose terminals on the harness plugs and connectors
Before you order
- Confirm the appliance model against the rating plate
- Check the existing harness part number against 720849801
- Inspect the connector layout and plug count on the old loom before ordering
