Actually Rocker , i’ve got the wrong machine. this doesn’t have an impellor jug. Sorry .
It may have a magnetic float switch for its levels though . When looking down at the sump , there might be a small cover in the 5 o’clock position . If this lifts off , you might find a small magnetic float under it. These can sometimes get gunged up with grease and crap , hindering the floats travel . Remove the float – REMEMBERING WHICH WAY IT SITS – clean out the float channel and refit . This could help .
