Waste water sensor

We have not owned our Malvern for long. We are away this weekend.  Before leaving filled fresh water and ensured waste was empty.  This morning at 5.00am it started raining.  At 5.30 I was woken by an alarm.  Checked the control panel and it says the waste tank is full. How??? I did some washing up and a few hand washes but that was all.

waste water levels are always incorrect in my experience.
Just drain tank at every opportunity.

Does it really need an alarm to tell you the waste water is full, can you disconnect it and do as Micky suggests just empty the tank regularly. Why manufacturers fit these useless gizmos defeats me, from what you say almost certainly it is nowhere near full!

"Key beep – pressing the key beep toggle button switches the key press beep off and on. Water level alarms – pressing the water level alarm toggle button switches the water level alarms on and off."

Don't know about the EC500.

Yes - it can be turned off on the EC500 too - via the EC480 panel above the door (in my Broadway). Access the 'Advanced Settings' and in there is an option to turn the water alarms off. I did this with mine to silence the same waste sensor issues.

"To access the advanced settings, on the home screen (the one with the company / brand logo), press and hold the up and down arrows together. Continue holding these buttons until the screen changes.


To scroll through the various settings use the up and down buttons. To change a setting press the select button (left arrow)."

Are you Sure you did not leave a tap turned  on

We had the sensors cleaned twice on our Broadway FB in its first year but it didn’t take long for them to start showing the tank was full again when it wasn’t. In the end I disconnected the wiring and emptied frequently.

Yep I had to do this today when I knew for definite the tank was empty as on driveway with the waste tap fully open and no more drips to be had. Originally showed as 50% full permanently when bought (known fault) then when I cleaned and flushed (trying to fix the problem) it started to show as 100% full when empty with constant alarm every time system was switched on.
Fresh water tank usually goes from 75% full to 25% without ever seeing 50% as well looks like the water sensors are a little bit inaccurate to say the least.
