Bosch dishwasher i have dishwasher that seems to progress to fast through cycle and does not heat water leaving dishes dirty. Is it likely to be timer unit or heating element Thanks

It might be your dishwasher detergent. Try adding some TSP (tri-sodium phosphate) to your detergent.

-Sounds like the pump is not working properly or the drain line you connect to sink directly instead to the breath cap before to the sink. Or the breath cap locate too low.
-Make sure the breath cap is mount higher than the line to the sink. (Or as high as possible) This is to prevent any water from the sink pour into the dishwasher.

Good luck

Hi there,

Unfortunately, it seems that the heating element has failed. The dishwasher uses steam to heat the tub to dry the dishes. I suspect your dishes are also being washed in cold water.

To check this, please run a regular full wash cycle. Allow the washer to fill with water and run for about 10 minutes, then open the door and feel the water temperature in the bottom of the washer. If the water is cold, it's more than likely the heating element has failed.

There are other possible faults which would cause the element not to heat, but these often prevent the dishwasher from completing the cycle. If the water is cold but the dishwasher still drains the water at the end - and completes the cycle - the heating element has probably failed.

Please try this simple test for water temperature and let me know if you need further assistance.

This is normal with a Bosch. They don't really vent out when they heat, and use a type of evaporation technology to dry the dishes. Best bet is to make sure first that the filter in the bottom is clean, (the little circle thingy on the bottom, turn it a quarter turn and pull it out, run it under cool water till it's clear, then put it back in the same way.) If the water is bothering you or is beginning to make a bit of a smell in there, leave the door cracked a little after you empty the dishes out. unfortunately though, it'll always leave water in the bottom. European technology.

If the dry cycle has a problem, check these:

Heating element
Drying fan
Thermostat
Heating element Your dishwasher has an electrical heating element that helps to dry the dishes. If the element is burned out, the dishes won't dry properly, and you need to replace the element.

Drying fan Many high-priced dishwashers have a small fan that blows air or heated air into the dishwasher to speed up the drying process. If the fan is defective, you need to replace it.

Thermostat Some dishwashers have a thermostat that monitors the drying temperature. If the thermostat is defective, the heating element may not cycle on or off properly. If that's the problem, you need to replace the thermostat.

this dw to save energy works this way- the final rinse will reach a temp of 161 F . the dishes have to absorb this heat. when the cycle is complete the dishes become a heater in themselves radiating the heat they absorbed during the final 161 F heat. If you have any tupperware or plastic dishes in the unit they will not absorb heat therefore not radiate the 161 f temp need to dry all the dishes. try to avoid plastic items and they must always have jet dry. this is the european way of conserving energy. on the old ge or whirlpool they had electric element in the bottom that would bake the dishes dry ....not these..but they do save alot of energy.. it helps right after a cycle to crack the door open release all the steam from the unit

I was able to fix this by using rinse during the cycle.

Hello,
Welcome to fixya,

You said, you have a whirlpool quiet partner dishwasher that is not getting even light food residue off the dishes. Cycles seem to be running and progressing normally, tho you do not think the water is spraying from the arms with adequate force.


I have the same machine.
And I notice if I leave the dishes in the sink rather than rinsing them off and putting them directly into the dishwasher, (Like My Wife says to do). That sometimes I have the same problem.
So I bought Jet Dry, and filled the holder. It's a small sometimes clear plastic knob that unscrews out above the soap dish.Fill it once a month!
Do you put the detergent in both cups or only the closed one?
1. If the load is not real dirty you should only have to fill the one with the door that closes.
If it is real dirty then both. To always use both is a waste of money!
2. If your hot water heater is far from your dishwasher, let the hot water tap run a minute till it comes out hot, before starting the dishwasher.
3.If the dishes or pans are very dirty and or baked on use hi temp scower and heavy or potscruber for those loads.

I use heavy wash and hot temp scower if the stuff is relly messy or dryed on.
And for baked on HI- temp scower and pot scruber which sprays harder.

You will have to experiment a little to see what works for you.
You will find it washeing good after you find what works for your families dish habits!

If you have any more questions let me know!!!

Just bought a Bosch dishwasher and we were told that they have no heating mechanism to dry the dishes, which is why they are more energy efficient.  You are supposed to leave the door closed for at least one hour after the cycle is complete.  The heat that has built up inside during the wash cycle will dry the dishes.  It is also recommended to always use JetDry. If you follow this advice, the dishes will come out fine.
