New World DW60 dishwasher not working originally had E4 fault Power comes into the PCB the switches and led's light up but nothing happens. After about 5 mins there is a short beep. Does not show any error codes, New World sent a replacement PCB which made no difference except now have no error code. Circ pump, inlet valve, heater, drain pump checked independantly all worked.

You have an error code which I think is a leak error.

Hi,

from what I'm seeing for the dishwasher, an E1 error means that the door is not properly closed. So, please look at the door of the machine to make sure that nothing is broken or that the dishwasher isn't too full. Thank you.

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

I'm assuming its a fisher and paykel, you will certainly need more info. Do you have an led display or 3 buttons and lights. Any fault codes, flashing beeping when buttons are pressed etc. If everything is normal no unusual beeps lights etc but nothing AT ALL happens when you press start it is the door 'switch' which is actually a light that is reflected through a plastic prism and back to itself ( originates from the board) check the prism top right drawer frame. Just compare to working drawer. If not more info required.

Hello, my dishwasher gorenje pms 60 l show specific faulty code. Both LED blinking symmetrically. Serviceman doesnt know. Please help me with this problem. Thanx.

Sounds like the drain pump has jammed - probably a bit of broken glass or a fruit pip, etc. isolate electricity supply, lie the machine on its back, after removing as much water as possible with a sponge etc, remove the base plate if fitted and the small drain pump should be removable, either secured with screws or just a simple 'twist' bayonet cap fixing. Check for blockages / foreign bodies in pump.
If not pump, ie you can hear it running on drain cycle, check drain hoses and plumbing for blockages. Remember there are usually two pumps, the bigger one is the wash pump. Some machines use 1 pump only, and reverse the direction of rotation for wash / drain. A foreign body in these pumps often rips all the rotor vanes of and you will need a new pump.

i made sure drain hose was not blocked found gunk at bottum , but to reset alarm e4 , had to drain dishwasher put it on its side - must have remove an airlock. checked turn on and e4 had gone , all ok now suggest rinse all dishes before washing

To clear the fault you need to remove the two baskets from the dishwasher.

Slide it out from under the worktop and lean it forward to about 45 degrees.

If it is already full of water, turn on the power whilst pushing the programme button, this sets up a pump out program

1. (Lamp may light and go out) suspect bad lamp part # 915P020010 2. Check for 12-volts DC at J-9 connector pin 4 on the Engine Driver PCB, if missing check for an open F9A09 on the Power PCB, if it is open replace F9A09 part # 283P127060 and the Light Engine part # 939P977010 3. (Lamp may light and go out) Check for 5-volts DC at J-9 connector pin 1 and 2 on the Engine Driver PCB if low or missing check C9A37 and C9A38 both 3300 UFD 10 V part # 181P732040 on the Power PCB (part # 930B921002) 4. At power on the lamp turns on and off three times and then the unit shuts down with a red lamp LED (lamp error). Replace the Light Engine part # 939P977010 5. Lamp enable line at J14 pin 6 does not switch to 5 volts after turn on, 12 and 5 volt supplies are good. Suspect the Light Engine part # 939P977010 6. Lamp enable line at connector J14 pin 6 on the Engine Driver PCB switches to 5 volts after turn on and does go to 0-volts (low) after 5 seconds, 12 and 5 volt supplies are good. Suspect the Lamp Power PCB (ballast) part # 939P978010 7. Lamp enable line at connector J14 pin 6 on the Engine Driver PCB switches to 5 volts after turn on but does not go back to 0-volts (low) after 5 seconds, 12 and 5 volt supplies are good. Suspect the Light Engine part # 939P977010

This dishwasher uses the program lights a s a fault code. Usually it is due to food jamming the impeller. If you are competent you can get at it from underneath. Mine was under warranty when this happened and the engineer was heard to say, 'this is a dishwasher not a waste disposal'. The engineer cleared it with a wire coat hanger down the drian hole inside the machine. Not happened since we really scape off plates.
