I replaced the control assembly and the board control,with parts from appliance parts pros. and it did not solve the problem. I normally use the quick cycle and air dry.It will work for a few minutes and when it drains for the first time it will switch to 99+. Is there another part that could be the problem?
Perform the water/service test as instructed in the Tech sheet. Post the results.
