Im have an issue and was wondering if anybody else has experienced this. lastnight I had the Wp40 set on H3 everything was running fine. I came down stairs this morning to find the H3, S3 and sensor lights flashing (sensor is not in can't stand it) The pump just does a very short pulse every couple of seconds. I noticed that if I unplug the pump from the control unit the lights go back to steady. Anybody have any idea was to what's going on. I had to head out to work so I didn't really have time to do much trouble shooting.
