I think I narrowed it down to the control board but want to confirm before I spend any more money. Received OE error. Checked all piping for obstruction. None. Replaced pump with new. Still nothing. Found service mode, checked water level frequency and pump operation. Frequency 67, not good. No pump operation. Checked pressure switch. Ohmd out at 23.7. Good. Tubing doesnt appear blocked or kinked. Checked pump voltage at harness when pump should operate. 57V. Not good. So am I good to purchase new board?
