Not working on waste tank and only seems to work on fresh water tank when it's full.

Any ideas?

On our hymer in top of each water tank there is a sender unit. it consists of 4 ( i think) stainless steel probes of different lengths that are in the water. try cleaning them, if they are gummed up they dont work reliably, should be able to unscrew access hatch and reach hand inside, you may choose to use someone elses hand in waste tank.......

clean the probes.. the ones in the back tank will be covered in crud.. the fresh water ones probably have limescale on them ..

they are mounted on the top,

As stated above. I find a good rub with a green plastic scouring pad does the trick. Preferably with different pads for each tank. :eek:

Gave my fresh tank a going over 2 weeks ago, removed all the accessible pipe work, washed out any black mold and cleaned all the probes with a "greenie" scourer, now reporting the correct level on the control panel.

Going to do the grey tank probes soon, but so have worked on the basis that if the sink won't empty it's time to open the waste gate. :rofl:
