What it is
The cable - pump predisp / terminal block (M3) is a Potterton Commercial wiring component used to connect the pump to the terminal block on Sirius 2 and Sirius 3 commercial boilers. It carries the pump predisposal connection within the appliance wiring loom. The part is supplied under manufacturer part number 7660976.
Signs this part needs replacing
- The pump runs intermittently or not at all while the boiler is otherwise calling for heat
- Visible heat damage, melting or discolouration at the cable or terminal block
- Loose, corroded or blackened terminals that will not make a secure connection
- Cracked or perished insulation on the cable run
- Repeated faults traced to the pump wiring rather than the pump itself
Before you order
- Check the boiler model and range against the fit list to confirm compatibility
- Confirm the existing cable and terminal block connector pattern and M3 designation match the part being removed
- Inspect the pump and its wiring for any further damage before fitting, so the fault is not repeated
