Grundfos Sololift 2 WC-1 not working

[Jazzguitar]

I have a grundfos sololift 2 wc1 macerator that isn't working. It's about 3 years old. When the toilet flushes the bowl just fills up but the motor does not kick in. There is power going to the unit, The macerator motor/pump turns freely. I took the motor apart in the hope that there may be debris, but nothing preventative(Just hair wrapped around the spindle). The small trip switches are in the correct position. There is power coming from the large capacitor and from what i assume is the pressure switch

Any advice on getting it working would be most welcome.

Thank you

Could the U-bend of the toilet pan be blocked and stopping water entering the pump or could the air vent be blocked off to stop any bad smells.

Just for the benefit of members on this forum, the issue has been tracked down to an electrical fault

Missed the bare wires and screwed down on the outer sheath did they.
