Water pressure in dishwasher too high

The dishwasher may use the heating coil to increase the water temp, Also utensils fall into the bottom of the unit and can melt. The heater coil may be about to fail and when this happens the temp increases. The filament inside the coil may have worked its way to the outer shell. Last but not least, the pump motor could be overheating.

Most dishwashers have safety thermal switches in place. If your dishwasher heater rise up above the normal temperature then this safety will burned out stop the runaway heater. Having said this

a) May be your timer is stuck. Is it mechanical or electronic. If mechanical you will see the timer not reaching end of cycle.

b) Sometime light weight plastic dishes fly off rack in wash cycle and land on the bottom of dishwasher touching the heater. Of course these will melt or burn when the heater comes at towards the end of cycle. THIS IS COMMON.

You will probably have to replace the heating coil in the bottom of the dishwasher to get rid of the smell. The coils aren't that expensive and replacing them is an easy job. Hardest part is getting the dishwasher out from under the counter to do it.

I am assuming the dishwasher is not working.

You will need to check where the plastic has come from. The temperature has to be very high for the plastic to melt. This can happen if the dishwasher heater has been on with no water in the dishwasher. Normally the controller should not allow this. Also the thermostat should cut in to prevent the temperature from going high.

Most likely it is not plastic but a problem in the wash pump which is causing some residue to circulate in the water and deposit on heating element.

In any case, try to scrape off as much of the material as you can and then run the dishwasher with a Finish dishwasher cleaning kit. The instructions are on the kit label.

Hope this helps. Please rate the solution.

the drain is plugged,when it goes into defrost the ice melts on the evap coil,it should go down the drain line to the bottom where the compressor is and evaporate from the heat but your drain is blocked and the water is sitting there and freezing up.you have to take up the fridge floor and get at the evap coil and first melt out all the ice with a hair dryer,if you have a shop vac you can vac up the water as it's melting,watch out with the heat from the hair dryer,you can damage the blade on the fan and damage the styrofoam,don't keep the heat in one spot to long and try not to open the drain hole till last,if you do and some of the water goes down the drain the pan on the bottom will overflow from to much water,once you melt out all the ice you have to clear out the drain line,i use a steamer,it cuts through whatever is in the line,also on some of the machines if you look at the back of the fridge there's a plastic trap that you can remove and clean out that the melted water runs through,i use a plastic wire tie to snake through it but your machine might not have this,some guys say a turkey baster works to blow through the line but whatever you use when you're done pour hot water into the drain,if it goes down then you know the drain is clear.let me know what you find

Below is a website with information about your dishwasher. It says it has a condensation dryer which means it dries the dishes using the heater coil in the bottom of the unit. This is a very slow process which continues to dry even after the unit has run all of its cycles. Usually over night they should be dry but any puddling water left on the dishes such as an over turned mug or cup will still be left on the dishes. The drying is done in this way to prevent damage to delicate glassware or melting plastic items in the unit. There is no dishwasher available that can fully dry the dishes due to the possibility of damaging your dishes.

It is a problem with the water heating cycle, the dishwasher pauses after it has filled with water, waiting for the water to reach the pre-set temperature.
A thermic sensor will allow the machine to restart the cycle after the water reaches the required temperature.
In your machine the thermostat is defective and the machine waits too long, that is also the reason for the too high temperature melting plastic.

Hi amsaunders5,

I'm Harvey the Master Plumber.

Your problem is: Children tried to surprise you by doing dishes. The plastic spatula melted and stuck on the heating coil on the bottom

This is a common problem. First, thank the children, it really wasn't their fault.
It's going to take some effort but you'll have to scrape/remove the plstic from the element. Replaceing the element is not a repair I recomend for the average homeowner.

Feel free contact me again!

have experienced this problem on some zanussi machines. what is happening is that the machine continues thro cycle thinking there is water in machine when there is not. can be caused by:
slow pump rate caused by blockage especially near the drain pump inlet
faulty pressure stat
