Dishes are not getting clean.

Water flow seems to be low in washer. Is there a filter in the supply line? Is the pump probably bad? The machine is 13 years old.

Dishwasher don't have "Filters" like refrigerators. What they do have are water valves like refrigerator ice makers. They a generally located in the bottom left front corner of the machine. Some of the earlier machine have a "wire screen" mounted just inside the inlet portion of the valve to catch sand, grit and such. Either way, replace the water valve and you should see a noticeable increase in inlet water flow.

Now if you are talking of water flow while machine is in the actual wash mode the you have a "pump" problem. If this is the case, and you really & I mean really know what you are doing then you can buy the parts to rebuil this pump. I don't suggest that you do that, we tech don't even do it. The pump comes as a complete unit, easy in and easy out. Pump motor number for this machine is 675748A, list for 162.08 today ( always subject to change over night). If you replace motor be sure to replace gasket # 717000. It must be replaced any time the motor is removed from base housing.

Low flow rate


You probably have debris clogged in the impeller. The pump has to be opened to clean or repair the impeller.

Where is the filter located and how often do you have to clean it?


Most washers have screen filters where the hot and cold water lines connect. The condition of your water supply would indicate how often you clean these screens. If you notice a decrease in water flow into the tub you should clean the screens.

Shut off the hot and cold water supply lines.
Drain the pressure from the lines by turning the timer dial through the fill cycle in both hot and cold water modes.
Remove the hot and cold water lines from the back of the washer.
Look for a screen inside the hose coupling or the washer inlet.
Remove screen and clean using a wire brush. If screen is damaged get a replacement at a hardware, or home improvement store.

Water will not drain completely/or at all from unit.machine cycles thru all stages, dishes seem clean but lots of water left in botton of washer.


The filter is probably blocked.


It is inside the base of the machine.


Take out the filter and clean it and also clean out the filter well as that can also hold quite a bit of debris.

My washer works great but takes forever to fill, I have A good water supply line, is there A pump in the washer? or could something inside the washer be plugged???


Hello Friend, Your problem is simple. Your water inlet valve screen is clogged preventing the water from flowing at maximum pressure. here's what you do: just remove the water supply hoses at back of washer and look inside the hot and cold inlet openings that you just removed the water hoses from. You should see a filter screen in each of them. remove the screens, clean them or just replace with new screens. Also check each end of water supply hoses for the same type of filter screen and clean or replace them as well. Happy to help, Tim.

I get a check water tap error 2 to 4 times a load


I have this problem. This code is due to restriction of water flow. In my case, we have sand in our water, and I have installed a filter between the water line and the washer. When it gets clogged, the flow is restricted and the Check Water Tap message appears. Your washer has filters on the back of the washer itself that may be clogged and need cleaning (which is why I installed the water filter between the washer & water line to prevent it from getting into the washer filter). Your washer manual shows you how to check/clean them. Also, you may have low water pressure during summer months due to lawn watering in your area that could cause this lower water pressure.

GE Dishwasher - poor cleaning


I believe there is a screen/filter on the water line before or at the water fill valve. If that gets plugged it can restrict the flow. The fill valve can also fail/get plugged and restrict the flow.
Also, dishwashers usually have a level sensor to tell when there is enough water to do the wash. It may be a float inside the tub that operates a mechanical switch or it may have a hose to a pressure sensor. Either type can get greasy/dirty/plugged and as a result cause improper water levels.
Check both the water supply filter/fill valve and the level sensor. One or both of those may be involved.

Not enough water Pressure to clean dishes, 6yr old Bosch


Replace the pump, if you go through the trouble of repairing the pump and all the disassembly and then more problems will probably ensue. As far as location it is usually located under the washer. Accessed through the front service panel. Make sure you follow all safety procedures #1 being unplug the washer or turn off breaker prior to proceeding.

Water seems to be hot enough, drains properly, arnms not blocked, dishes not being cleaned at end of cycle. Almost seems like it is skipping the wash cycle.


Hi smiller8565,
There is 3 basic problems that will cause a dishwasher to not clean the dishes. You can check these problems and see if any will solve your problems.
1: If there is water or suds left in the dishwasher after the cycle is complete. This will cause dirty water to be used in the final rinse and the dishes will not get clean.
2: The pump that supplies water to the spray arms is jammed or defective and unable to pump the water properly, thus causing the dishes to remain dirty.
3: Timer, the timer is not allowing the machine to work in the wash cycle.
The solutions for these 3 are as follows.
1: check the drain line for blockage, if you have a disposal make sure it is clear and water flows down the drain properly. If you have suds left in the dishwasher, clean them out and run a couple cycles with not detergent to rinse away the old suds.
2: Look down in the bottom for any obstructions in the pump. Popcorn seeds, broken glass, etc.
3: If the unit is skipping the wash cycle you will most likely need a new timer or control assembly.
Good luck and I really hope this will Fix Ya

Dishes not thourghly cleaned on top sheelve


generally dishwashers rely on the pressure supplied by the water supply line. check to see if it is enough or if inlet pipe is of sufficient diameter for needed flow.in some instances i know of seperate lines needing to be run directly instead of coming off of supply to sink area.
