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
and allows it to operate again. The
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
