The flow switch is not closed or the low water cutoff (LWCO, optional) was tripped. This is an automatic reset error and as soon as
flow is proven this error resolves itself. To identify the safety that is open set the multimeter to Vac and measure the voltage from
one contact to ground. The contacts produce a 24Vac when the circuit is closed.
