Dishwasher problem Hi We have a Whirlpool GU 2300, the machine has stopped and is the clean LED on the control panel is showing a 7 pulse sequence which I guess is a fault alarm. I have tried resetting, checked the door switch and looked at the pressure sensor at the drain pump outlet. I changed the heating element and fitted an uprated control card earlier this year. Any ideas?

7-1 heating circuit problem control programmed to shut down machine when no rise in water temp during heat cycle, you either have an open heating element or wire burnt a shorted thermistor or a bad control not outputing 120VAC to the heater you can reset the control by placing the machine into diagnostic hit cancel button to turn off all the lights press heated dry-normal, heated dry- normal within 6 seconds lights should come on press cancel unit should start it will run till same part of cycle reached and lock out again if it has not been removed the little black panel below the door remove should have the tech sheet in a plastic pouch which explains how to check the components mentioned earlier,

Do you know if your machine have an anti leak system?

1) You must change the wire with the same diameter, and solder well or put some connector. 2) Test for some corroded contacts, and clean with special spray contact cleaner. 3) Retight, or resolder, or tight any connector very well. 4) You must shure the dishwahser is only 1 circuite, in other words, only this machine will be work, NOT OTHER, this can cause to recharge in amper the equipmet, and overload.5) Test the c. board, maybe is faulty. you must call to the service tech. There are probably some component failure that cause to hot melting the wires.

God bless you

Hi

If clean light is blinking 7 times then it may be an issue with heater circuit, door switch or wash pump. If yes then please reset the power to the dishwasher. After, 5 minutes check if you are still getting the same error. If yes, then it is a water heating fault. To resolve this error try pressing this reset sequence-- Heat Dry - Normal - Heat Dry - Normal or High Temp - Air Dry - High Temp - Air Dry or Hi Temp Scrub, energy saver dry, Hi Temp Scrub, energy saver dry. Now let the unit run for 2-3 minutes and then you press the Cancel/Drain button and allow it to completely drain and reset.
If this doesn't work then it's an issue with the wash pump not pumping the water past the heater efficiently or due to lack of water to heat. Please make sure that heater is not open circuited and is heating the water efficiently. You'll have to check the heater using a multimeter; the meter should read between 3000 to 3300 ohms (Use multimeter on Rx1 ohm setting). If heater is fine then make sure water pressure is optimum and fill valve is working fine.

Hope this helps... Please post back if you need more information.

Hi, this is an indication that the water did not heat properly. Follow this link to some instructions I put together to help solve this and reset the control so you can use the machine again.

whirlpool adg4952m is reading F2 and not working

Control is programmed to stop running and not allow any further cycles if it detects a water heating problem (no temperature increase detected in heated Main Wash on 3 consecutive cycles). Control blinks the Clean LED 7 times repeatedly and disables the Start/Resume key until cleared. Running Diagnostics clears the control and allows it to operate again. The water heating problem must be fixed or the control will stop running again. See potential causes below. Heater circuit problem: ■ Open in heater. ■ Open connection or component in heater circuit. ■ Faulty heater drive circuit on control. 1. Check operation of heater in Diagnostics cycle. 2. Unplug dishwasher or disconnect power. 3. Check resistance of heater and all components and connections in the water heating circuit or heat dry circuit.

dont forget to vote hope this helps thank you

The cleam light blinking means that the unit was not able to reach a proper heated wash cycle. Either your heating element failed orthe actual sump/pump motor system has failed. Check the element in the botton and see if it looks broken anywhere. If you can see a broken spot, you will k now that is the trouble.

Good Luck!

Watch the light closely. If it blinks 7 times then pauses, this indicates a heater or door latch issue.
Press the following buttons in sequence: Hi Temp Wash, Heated Dry, Hi Temp Wash, Heated Dry, Hi Temp Wash.
If this doesn't work, check the tech sheet. (should be stuck to inside of the bottom toe panel)

All lights should illuminate then a diagnostic sequence will start.
Listen carefully, as soon as you hear the water begin to fill, open the door and feel the heater. if cold, check the heater for continuity (should be around 10ohms)
Also, bend the door catch on the dishwasher tub downward, this will engage the door latch better. Don't bend too far as it will hit the door while closing.

For KitchenAid Whirlpool KUDS01FLSS0 -- When the clean light is blinking or flashing 7 times in a row and no other front panel controls will work, do the following:
push SaniRinse-EnergySaverDry- SaniRinse - Energy Saver Dry
(Try the Heated Dry button if you don't have a Energy Saver Dry button)
All the lights will then come on as this will put the unit into diagnostic mode.
Then, push Cancel after about 10 seconds. You are no longer locked out. Run the dishwasher normally.
