My Candy DFI Plan shows E3 and stops washing after 10-15 minutes. The problems started because electronics( I swithed with new) than I change the water pump, the heater, the thermostats and when is on,...


E3 - Water heating time out or fault

The dishwasher has failed to heat with water in a reasonable time or has failed to detect the water heating element.

Check water heating element wiring
Check water heating element
Check wiring to main control module

Normal wash cycle is over 2 hours?


Hello there
If your dishwasher's cycle times are too long, check these: Water pre-heating Cycle not completing Water pre-heating Your dishwasher may pre-heat the water. If so, and if the water entering the dishwasher is cool, the heater may take up to half an hour to heat the water. To avoid the wait, increase the incoming water temperature before turning on the dishwasher. Do that by running the kitchen sink faucet until the water runs hot. Or increase the temperature of the hot water to the entire house at the hot water heater. Warning! To lessen the risk of scalding, don't set the hot water heater temperature higher than 120 degrees Fahrenheit.

Asko dishwasher d3530. The water in the dishwasher is not hot.


Generally speaking, dishwashers don't heat cold water on their own. Be sure the dishwasher is connected to a hot water supply and that hot water is available to the dishwasher at the START of the cycle.

Often it takes hot water several seconds for house plumbing to deliver hot water to an outlet. If the dishwasher is connected to the kitchen hot water supply, run the water in the sink until the water runs hot before you start the dishwasher.

Dishwashers often have heaters to heat the water even hotter than most home water heaters, but they are not intended to heat cool or cold water. You MUST furnish hot water to the dishwasher from the time the cycle is started.

I've seen houses that take so long for hot water to reach a faucet, the dishwasher is already full (of cold water) before the first drop of hot water reaches it.

Good luck. Hope this helps.

Water level below heating element and element does not appear to heat


Make sure the drain hose high loop is installed properly, normally you have this in the sink cabinet high up. Otherwise the water inside the machine may drain "by itself", leaking through the inactive drain pump during the wash cycle and cause this and other troubles.

Running time of dishwasher


he cycles times are too long If your dishwasher's cycle times are too long, check these:

Water pre-heating
Cycle not completing
Water pre-heating Your dishwasher may pre-heat the water. If so, and if the water entering the dishwasher is cool, the heater may take up to half an hour to heat the water. 

To avoid the wait, increase the incoming water temperature before turning on the dishwasher. Do that by running the kitchen sink faucet until the water runs hot. Or increase the temperature of the hot water to the entire house at the hot water heater.

Warning! To lessen the risk of scalding, don't set the hot water heater temperature higher than 120 degrees Fahrenheit. 

Cycle not completing See "The cycle doesn't complete" section. 

The cycle doesn't complete If the cycle doesn't complete, check these:

Water-heating cycle
Timer
Water-heating cycle Many dishwashers heat the wash and/or rinse water to a higher temperature, as the cycle calls for it. In these cycles, the dishwasher pauses after it has filled with water, waiting for the water to reach the pre-set temperature. What happens next, depends, as follows:

  • On some units, the pause is timed and the unit continues after the allotted time.


  • On others, the cycle can't continue until the water reaches the higher temperature. If you have this type of dishwasher and the water isn't being heated (say, because of a problem with the heating element or thermostat), after the unit stops at the heating cycle, it never continues. When you repair the heating-system problem, the "cycle problem" is fixed too.


Timer Timers don't often fail. But if every other part of the dishwasher seems to be working properly and the timer knob seems to be stuck in one place--doing one function continuously--the timer may be at fault. Dishwasher timers can't be repaired. If yours is defective, replace it.

Not heating water


Is this an old or newer dishwasher many newer models will not bother trying to heat up the water if it does not come in hot enough there is a temperature sensor, if the water is cold heater will not come on because it will take it too long to heat the cold water.

I have a Bosch SHV55M03GB dishwasher which does not heat the water. The programme cycle also sticks at the last minute. Any ideas, heater element or control panel? Thanks.


If cycle proceed normally after waiting for a while, then the control is probably OK. It stands by a while because it does not read correct temperature before proceeding.

If the appliance is connected to both hot and cold water, open more the hot water faucet.

If the water is not heating at all, check heating element for continuity, using a tester.

If water is heating regularly, but cycle is still slow, check thermic sensor.

Here are more suggestions from Repairclinic:

The cycles times are too long If your dishwasher's cycle times are too long, check these:

Water pre-heating
Cycle not completing

Dishwasher not heating water


British machines are Cold water fed, and the machines heat the water themselves. American Machines are hot water fed.
