Help needed with F&P dishwasher draw not pumping out |

Hi everyone, I have a F&P single dishwasher draw. It is not pumping water out. I have taken the filter out and pulled the impeller out of the bottom and no blockage that I can see.
When I try to force water down the end of the drain pipe there is total resistance. Is this resistance a blockage or is there a valve system in the pump that opens to pump out? I have pulled the draw out and put it on its side. There is a plastic cover which I am having difficulty to remove. I figure if i can get the plastic cover off I can disconnect the drain hose from the base of the draw and check for blockages. I am also not sure if there is a seperate drain pump or if it is an all in one pump/impeller that sits in the bottom of the tub where the spray arm sits. I am having difficulty getting technical information or schematics on the internet. Any suggestions would be very welcome. Cheers Simon | ||

Most F&P Dishdrawers
Work in a similar way. Before you remove the cover and then the pipe see if there is a blockage at the connection under the sink. You won't be able to blow down the pipe as there is a rubber flap that seals the end of the pipe near the outlet it prevents any back flow of dirty water from the sink.
Also have you checked the groove under the filter that goes from the filter to the impeller ? All that needs is a pea and then no water drains. | ||

 There is no separate drain pump, or mechanical drain valve. The motor reverses the single rotor/impeller for drain vs. recirculate, as stated above. Debris can potentially clog the pump outlet port, which is somewhat accessible from inside by removing the filter. Try a turkey baster to flush or suction it. There is a non-return flapper on the outlet port of the pump housing. Removal of the drain hose is required to access it. There are multiple anchor clips on the wiring cover. | ||

Thank guys, very helpful suggestions. Model # DD608DFTX7
I managed to get the plastic protector off the bottom of the draw and disconnected the drain pipe from the base of the draw. There is a rubber non return flap valve so water wont syphon back in (hence not being able to force water down the distal end of the drain hose. One unit to pump out via the small impeller in the sump and the upper bigger impeller to power the spray arm. Absolutely no blockages anywhere. I put it all back together and did a rinse cycle and it pumped out at the end. Have to say it is not the strongest pump but guess it doesn't have to be. We inherited the unit when we moved into our house 3 years ago. I reckon it must be at least 10 years old. It has always been noisy when it pumps out. I wonder if there is an issue with the reversing of the motor to pump out. I will put it back in situ and see how it goes. May be time to get a new one :-) Thanks again, really appreciate all the suggestions/advice | ||

It has malfunctioned again
The dish drawer was working fine after I put it back in situ but after about 5 cycles the tub had water in the bottom again.
It tries to pump out but fails. It is noisy when pumping out and always has been. The impeller turns really easily by hand so seems there is nothing snagging it. When taking the impeller unit out and putting it back in I can feel magnetism. I guess the unit rotes by some sort of magnetic drive from the motor. There is no direct drive connecting the motor and impeller. New motor is around $250.00. Don’t want to buy new motor and it still won’t pump out. New unit is around $2,000.00. Double dish drawers are not much more. A bit of a conundrum. Any ideas on what the issue may be? Simon | ||

Perhaps post photos of the pump rotor. Try running the pump in drain mode repeatedly via diagnostic mode with the arm removed to observe if it sometimes doesn't rotate (although that should be apparent by sound). You can also pour water into the tub to directly test pump-out operation. Is the model perhaps DD60SDFTX7? What's the product code? | ||

Hi DADoES,
Model # DD608DFTX7 I would love to run the unit with the draw open so I can see if the impeller is running in reverse when it is attempting to pump out but so far how to do that has eluded me. The lock seem pretty tamper proof but any suggestions how to bypass the lock gratefully received | ||
