Noticed today no chlorine generating. Display is showing no flow.
Checked the switch with a multimeter and it's open circuit with or without the pump running. Ergo... bad switch.
Searching online for a replacement, there seem to be 2 different types (with the same part number). Are these 2 inter-changeable?
Also, the price varies wildly. From $30 on Ebay to $240 from our friendly neighborhood pool supply company
Fortunately, I still have the puck feeder in line so added my last 2 pucks to keep my chlorine up.
