My maytag Mod MDB8959 stopped mid cycle. There is power to the machine but no lights or response from the door controls. Any suggestions?

"Wondering if this model has had reliability issues with the circuit card." ...If by circuit card you mean the electronic control board, that part number is used in many other models as well. In my experience with these control boards, I believe they have a low failure rate.

Make these checks if you haven't done so yet...
Check for 120V (breaker). Look for loose/shorted wiring connection at the dishwasher's junction box. Check all wiring connections to the control panel, electronic control and thermal fuse. Test the continuity of the thermal fuse (part # 8193762). If that's ok, you have already replaced the control panel so the problem is likely with the electronic control board (part # 8564546).
Good luck.

Since water doesn't drain out ,it could be a clogged in the drain line. Often the problem is at the point where the drain line attaches to the garbage disposer or household drain line. You should remove this line and clear it form any debris in the hose or the hose connection. Be sure to reattach the hose before starting the dishwasher again. Good luck!

most likely you have a bad motor when replacing the motor ihave found it is cheaper to get the pump with the motor attached where as they charge you more money for just the motor or the pump seprately try allbrands appliance parts they seem to be cheaper
