SOURCE: Kenmore Dishwasher #587.... doing nothing but heat dry

The problem appears to stem from the float and float switch. The float is a mushroom shaped plastic part that resides on the bottom left, just inside the door. It appears that the float does not release the float switch, causing the dishwasher to think it is full of water, and won't allow the dishwasher to fill. It's a relatively straight forward repair, but even with a new part, the same scenario is likely to repeat itself until the float or float switch is modified by Kenmore.

The error message "Err" usually indicates that the wash program and option are not compatible. 40 degrees and 900 rpm Spin should be o.k.. I would try another wash program with no special options and see if the problem goes away.

Is the clean light blinking 7 times? If so this means you have a problem with your heating element
