Question about Dishwashers

2 Answers

Hello! My 3 yr old Bosch dishwasher (I think it is a SHE 43) is doing two things: 1) leaving a serious white film on dishes and glasses 2) leaving grit inside glasses on the top rack (always on glasses placed on the far back right of the top rack) I've tried cleaning the machine with hot washes with no dishes, vinegar only, but no luck. Any thoughts? Many thanks for your help!

    To clarify a few points - we are not using stale or clumping powder soap, and the dishes are not overloaded or improperly loaded.

    The machine appears to be draining properly (no water left in the tub when done). We have cleaned the little cylindral filter and the larger grate where the bottom spray arm attaches on the floor of the machine.

    I've checked both spray arms and there are no obvious cracks or splits.

    Thanks in advance for your help!

Hello. Since you have already cleansed the interior of your dishwasher, we must conclude that the problem is with the water itself. If you do not have a filter on your water, you may want to consider installing a dirt/rust filter, at least on the hot line that feeds your dishwasher. Also, you should consider draining and rinsing out your hot water tank as it may have accumulated gunk in the bottom of it. Joe

    Interesting thought. Here's what I am wondering - what about the grit in the glasses - only on the top right side? If it was the water, wouldn't that be on all the dishes?

  • jemcculloch Jun 07, 2010

    So - other thoughts? I flushed the hot water tank (wasn't terribly gunky - got some rusty water and some mineral deposits, but nothing dramatic) then ran a hot load with vinegar poured in. Then ran the dishes - still covered in a chalky white residue, plus grit left in the glasswear placed in the top rear right corner. I'm using the same detergent I've always used (now called finish, was electrosol) plus lots of rinse agent (we live in a hard water area).

Hi


Thanks for using FixYa. Please check that the Powder soap is stored in a dry environment and it is not stale and clumping together. Possibly try a different detergent like a liquid or gel. Also, make sure the dishes are loaded properly, or dishwasher is not overloaded. Dishwasher will fill with water up to and around the heating element. If water is more below the heating element, there is a low water pressure or a problem with the fill valve. Try & listen if it sounds like it is spraying the water around with enough pressure. For low water pressure, try to clean the screen at the entrance of the fill valve, sometimes the fill valve can fail and not allow the proper water into the dishwasher and may need to be replaced. And, check the spray arm and pump cover for splits or leaks. As the water is not draining please check that the drain hoses and drain pump are not clogged or kinked. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks
Rylee

    First of all please check the Water temperature by using a
    thermometer inside the dishwasher to measure the water temp. It should be as
    close to 125 degree F to 140 degree F as possible. Now try using the
    temperature boost feature if your dishwasher is equipped with this cycle
    feature and check if this will help your wash ability issues.

My GE dishwasher is 2 months old. The dishes are coming out with a film on them and the stainless steel inside has a white residue on it. I am using the recommended cascade products.


Do you know if you have hard water. It sounds like a hard water film. 1) purchase several applications of dishwasher cleaner from your local grocery store. Use them all back to back. 2) The only detergent I have found effective with hard water is called Somat. You may try your local appliance parts retailer for this. 3) The best solution is a water softener for your house.
To confirm if this is hard water, soak an affected glass or dish in the sink with 1/2 white vinegar and 1/2 water for a couple minutes. Then simply dry, if the film is gone its hard water.
