Leak Detector Troubleshooting
The installation kit for DWM-20A provides one (1) leak detector which will automatically shut off the water to the
dispenser if leaks are detected (assuming that its electrodes are correctly positioned and its alkaline battery is
charged).
However, very often leak detectors are activated by minor water spillage from the drain pan and/or a partially wet
counter. In that case a beep is clearly audible and the leak detector must be reset.
See the table below for leak detector troubleshooting and instructions.
