Our dishwasher (Roper built-in) (WU5750B1) has been acting very erratic the last few weeks and I am looking for suggestions as to what could be failing.

Last week, one operation did not drain at all, another operation the timer just made EXCESSIVE clicking noises and no wash occurred.

Today: First attempt, timer rotated using proper time frame with normal mechanical clicks, but no operations occured for the entire 'cycle'
Second Attempt, proper operation as should be, with minor water puddle in bottom (very little)

Additional notes....Timer does not feel stiff or unusual, We have only had a total of two cycles that did not drain over the course of about twenty cycles, The clicking timer with no other operations has occurred three times now.

My first guess is that the timer may be getting worn? Obviously I do not want to inivest in a new timer if that is not the issue. Since (as I understand it) the timer sends all the power inputs to the components at the required time I am assuming that this may be the problem since certain cycles, nothing has operated.

HELP please.

Gene, Thanks for the input, I will mention this to my wife also so that one of us can try this.

I went ahead and installed a new timer in this dishwasher.......No help it is still erratic in its operations.

Could there be a problem with the door switch? or the door switch wiring?

Any help would be greatly appreciated.
