No Green Light - No Amp Reading - No Chlorine Output

During the normal process of producing chlorine in the electrolytic cell, Calcium deposits will develop on the cathode electrode of the cell. This needs to be removed to ensure proper operation and chlorine production from the Watermaid unit.

Apart from cleaning the cell electrodes, it may also be necessary to clean the Gas Sensing Tang inside the Watermaid Cell. It too can develop calcium deposits, that need to be removed. It is not common, but in some cases can result in the Watermaid unit from functioning and producing chlorine.

Turn the pump off and close any shutoff valves if necessary.

Unplug the Brass Plug from the socket at the top of the cell. It should just pull out by gently twisting and pulling.

 

Look into the top of the cell. At the top of the cell you will see a short metallic strip, (the gas sensing tang) bent upwards. It is approx 1/4 inch long.

If this titanium strip has any deposit built up on it, clean it off with a screwdriver or other instrument, simply by scraping it clean. Acid / Water Solution cleaning may also be used, whilst cleaning the complete cell.

Please Note:  In the QT Model Cells, the gas sensing tang is located in the same position.
