Inspect Flowmeter
1.Open the control panel and take out PCB;
2.Unplug the CON27 wire(shown in below picture), then use the multi-meter Diode shelf to
test whether electrical pulse is sent out from two black wires while water is passing through
flowmeter, or not.
3. If there is continual electrical pulse, the multi-meter will send out sound “de” continually.
4.if there is no electrical pulse, the multi-meter will not send sound. In this case, it means
something wrong with flowmeter circuit. We should check the connection first. If the
problem hasn’t been solved by re-connection, we should replace the air breaker..
Access Flowmeter
1. Remove the baseboard, life baseboard, top panel and life side panel.
2. Remove the plastic nut inside tub, which secures the air breaker to tub.(Because
flowmeter is integrated into air breaker, replace air breaker if flowmeter has failure. )
3. Disconnect the wire and remove clamp fastening hose to air breaker.
4. Take out air breaker.
5. Reverse the above procedure to install.
