Heidelberg SM 72 Blanket washer Water Fault

Hi,
I’m looking for help because I can’t clear the water level fault on the blanket wash system. its flashing which mean low water but the water level is fine. It may be a sensor fault if someone could locate me to the correct sensor or area.
Thanks in advance

Lower, back side of reservoir.

 

Thank you, any tips on how to change it?

 

It's threaded into the resevoir, you should see a hex shape on body of sensor. This 72 Speedmaster may have a metal sensor body, later they were all plastic. Just mark where the wires were, and reattach new one.

 

Check junction box (where wires from sensors terminate) to make sure you don't just have a loose or broken wire.

 

Brilliant thank you, it’s snapped so I’ll have fun changing that.

Brittle from age and exposure. I’ve used a large easy-out/extractor.
