Hi,Welcome to Just Answer, My name is XXXXX XXXXX forward to helping you today.
is it blinking 7 times then repeating ?
this is brand new ? it appears the heater is this issue, heres what the service tech sheet says.
Control is programmed to stop
running and not allow any
further cycles if it detects a
water heating problem (no
temperature increase detected
in heated Main Wash on 3
consecutive cycles). Control
blinks the Clean LED 7 times
repeatedly and disables the
Start/Resume key until cleared.
Running Diagnostics clears the control
water heating problem must be fixed
or the control will stop running again.
See potential causes below.
there is a whole list of potential causes for this, since this is new I would not attempt any repairs it will void your warranty..
I would call for service as soon as possible. thanks Bryan
