Question about Bosch Dishwashers

1 Answer

Model SHU33AO2UC /40 The top rack leaves lots of residue and stuff on glasses. We had a repairman out, he cleaned out the pump intake, and we are careful to clean everything before putting it in the dishwasher. I have made sure all holes in the spinners are clean and don't crowd the glasses. We have also tried different detergents. The dishwasher is 4 yrs old and is used daily. We also use jet dry.

SOURCE: dishwasher leaves residue in top rack only

Most cleaning problems are caused by the dishwasher not getting enough water. It could be cause of the switch level, which control water level in the tub. The switch level is usually a diaphragm device with a small clear tube attached between the switch and the bottom of the washer's outer tub. I am not familiar with your machine, but if you will open the rear panel you will find it easily. Be aware you should discoonect the power cable !!! Clear the tube (attached between the switch and the bottom of the washer's outer tub) from any obstruction.In case it will not solve the problem, you should replace the switch. Good luck !

SOURCE: GE Profile Dishwasher (5 years old); Leaving residue on dishes

There is a new product out that actually filters the water going into your dishwasher. My dishes came out amazing after the first load. No more cloudy glasses. I was very impressed. Who knows whats in the water cleaning your dishes so i thought this filter was great. It is very affordable and you can get it at www.dishwasherfilter.com. Hope this helps some people.

Although I previously posted with the same problem of a film on the dishes after cleaning, I did find a section in the owner's manual which solved my problem. Lift up the rinse aid cap on the inside door - the factory setting is on "4". The rinse aid works in conjunction with your local water, which has variations in it's hardness or softness. When your dishes are streaky, lower the rinse aid setting to 1 or 2. If your dishes are spotted, raise the rinse aid setting higher.

Yes, you will need to purchase a set of torx style screw drivers at your local hardware store. Remove the upper and lower spray arms and clean the debris out of the spray holes. Remove the screws that hold the filter in place and remove the gunk out of the sump. In the future stop using gels or gelpacks, just use electrasol powder or cascade powder. The gels and gelpacks clog up dishwashers like you would not believe. Run some Lemi-shine through the machine on a monthly basis, Lemi-shine is available at most walmarts.

The dishwasher is not cleaning the plates and glasses as should, leaving a lot of residue on everything


It sounds like water isn't being forced through your spray lines, which could be a result of either you trap being clogged or the sump pump not working. It could also mean that your heater element isn't heating the water hot enough for it to clean.

If it only the upper rack then it could be a blockage for the upper sprayer, but if it is throughout the machice, then it would either be the sump pump, trap or heating element as the most likely causes.

Dishes aren't clean, lots of white dried on stuff on top of glasses and dishes


The problem is most likely that there is still water residue at the bottom of your machine. If the machine is not fully drained it picks up some of the residue and sprays that onto the dishes during the final rinse, leaving an unhealthy and unsightly film on everything.
Remove the bottom strainers plates and make sure that the outlet pipe is not kinked, that there is nothing obstructing the pipe or the pump or selector valve. If possible back flush through the outlet pipe and try draining the machine once more before using it again.

My dishwasher is leaving a lot of residue on dishes


I had the same problem and fixed it by disassembling the lower spray arm and return filter, and cleaning all the junk out.
Most dishwashers have 'risers' that bring the water up to the top sprayer or arm located under the top rack. If the recirculating pump is plugged even a little there won't be enough volume or pressure to get the water up there.
Test this by putting a dry muffin pan in the top rack, flat, and running the dishwasher for a bit. If there is no water on the top (or the bottom) either the top sprayer or the sprayer arm underneath the top rack is not getting enough volume.
To fix this you need to clean out the screen and filter, where the water returns to be recirculated. If you don't have any confidence to remove the parts and clean it out yourself, get an appliance repair person to do the job.

Kenmore Dishwasher not cleaning dishes - especially top rack.

Either:
  1. not enough water gets into the dishwasher. check water valve, water level float and water pressure.
  2. the pump is clogged - there is water, the motor will run but no water is circulated. Check pump filters, check chopper and impeller.
Good luck,
