I have had my dishwasher for 3 years. In the past few days the tablet that i put in hasnt been disolving and washing the dishes. The compartment where you put the tablet opens its just the tablet doesnt disolve.

forget using the tablets. get the difi filtration system at www.dishwasherfilter.com. it will leave your dishes spotless and you do not need to add rinse agents or special tablets. guaranteed product or your money back

I am guessing you are using the Centigrade temperature scale ... which would be 149 degrees F. 149 is way hot in terms of regular house hold use. Probably just right for a dish washer.

I would expect most tablet detergent would disolve properly at this temperature and with proper water pressure in the machine. You should have plenty of both in this machine. May I suggest you give liquid dish washer detergent a try to see the results?

1. Check that water enters dishwasher.
2. Check that water is heated,tablet door will then open, this allows the propellor to shoot hot water at tablet to dissolve.

Your problem is very clear, you need to replace the wash tank heating element.

if the door opens and it doesnt disolve the water isnt hot enough

Check to see if your water is 140 degrees.

Is the cup opening to release the tablet?

I don't have a solution, but the exact same problem is happening with my dishwasher. Nothing is getting cleaned properly.

Did you manage to get the problem fixed?

It sounds like you have a water supply issue. If you are on well water the screen in the water valve may be clogged. You can access this, remove it and clean it on most dishwashers. It is located in the valve where the water hooks up to the unit.

Try placing a packet in the bottom of the DW and then start a wash cycle ( use the energy efficient cycle that does not use the heater to dry the dishes..).. if it is not disolved at the end of the cycle then your water temp may not be hot enough..Hope that helps..

Do not recommend premeasured tablets, usually too much soap. If pre-rinsing dishes use only 1 or two teaspoons of soap in the main wash cup..do not put soap in the prewash cup. Excess soap can cause oversudsing and make the soil sensor think the dishes are real dirty initiating additional wash cycles. Use rinse-aid for better drying performance
