    Thank you so much. Did exsactly what you said and it WORKS fantastic, niw I dont have to look for a new dishwasher.

  • Ron Johnson Jun 19, 2012

    Mate you are a champion. My dishwasher stopped producing heat two nights ago. In hindsight it has probably not been heating to its full capacity for several months. I removed the PC board and had a dry joint in the same spot as your image. Two small spots of solder and the dishwasher is working perfectly. I'm sure it has saved me hundreds of dollars and hours of hassle with repair persons etc... Thanks so much

Thank you this worked for me.

1st of all to be sure that the Heater element has not open circuited, checked the resistance of the heater element which was O.K. Then dismantled the control by unfastening top 6 Counter sunk screws on the front door and removed the PCB housing. The cables are terminated to the PCB via 6 push on sockets. The socket sizes being unequal, there is no chance of interchanging the cables during re-assembly.

PCB track feeding output of Relay was burnt out due to over heating. Soldered a short length of wire directly from the output of the relay to the spade terminal leg on the PCB.

See attached picture

You guys are blo....dy brilliant. I have put 2x heater elements into my DX302. The first time I think I got lucky - having the circuit board on the door probably banged the joint back into life but the second one - still no heat. After looking on this site BINGO. Joint as described 30 secs with the trusty Weller and all fixed. Unfortunately - I can't send back the "replacement" $85 heater I have but at least I won't be buying another one.

One think gives me the willies are those silly hose clamps on the heater - they are hard work. Why can't (I think price might be the issue) use worm drives.....

Thanks for this site - I'm just stoked.

Element surrounds short section of stainless steel tube on outlet side of pump (clamped hose section either side) Unlikely to be faulty, check circuit board for dry joint at relay.

Hi
I have the same problem with my 302.
I noticed the dodgy relay solder joints and have fixed them and confirmed the operation of the relay, but still no joy.
Does anyone have a service manual they would be kind enough to email?

    Ditto... for my dishwasher, a Westinghouse SB907, (which I've had for just over 10 years and up until yesterday, had performed very relliably), but the PCB is exactly the same as the one discussed in this thread. I removed the PCB and on initial examination, it appeared to be fine - no evidence of burning, nor any obvious dry soldered joints. However, bearing in mind what I'd read on this forum, where one or two others reported the same, I decided to re-solder all of the pins to the relay, as well as the beeper's pins (only 2 pins), which had gone silent (stopped beeping) about a year after I bought the machine. The machine now heats up and dries AND the beeper works again.. It is too early to tell yet if this repair was 100% sucessful, as the problem with mine was intermittent - i.e. it worked OK most of the time, but sometimes no heat. Last night was the last straw and decided to either replace te machine with a new one, but see if there was any DIY solution first. There was of course such a solution: right HERE on this fixya.com thread... I must admit that I'm a bit worried that there are other dry or unreliable soldered joints on the PCB, as re-soldering the beeper's pins proved it beyond doubt, so now wonder if something else will stop functioning for the same reason, but if so, I'll at least know what to do and how to do it - it's not a big job or a difficult one. If I'd not found this forum, I'd probably have wasted an awful lot of money (on a new dishwasher that I don't need) or, still have a malfunctioning, white-elephant in the space in my kitchen, reserved for a (fully functional) dishwasher! Thanks all of you - you have taken a big load off my mind...

The relay could be off because the thermostat is faulty. There are 4 wires to the thermostat . Does anyone know which trigger the relay to close?

Guys, Thank you so much for your info, i lost heat in my 302, followed your guide, 1st time I resoldered 5 joints, nothing, then I resoldered about 20 joints that were large enough for my shakey hands, BINGO, it now works so I believe there is a quality control issue with these boards.
Thanks again, otherwise I would be buying a new machine.

Great information.
Saved cost and mucking around under the DW to replace the heater element.
Simply checked and resoldered a few joints on the circuit board at the front and bingo. Problem solved.

Got 10 years out of the Dishwasher. Might get a few more.

    Some extra info before going into the circuit board.

    Remove the front control panel.

    Use a multi meter to measure AC Volts across orange and blue wires from right hand side plug.

    At power on it shows nothing (or about 3 or 4 volts).

    Once it is running and filling up it shows 240 volts (or there abouts).

    After filling from mains water this drops to 0 (zero).

    In the last five minutes it rises to 240 volts again.



    If it doesn't do this I would suggest a problem with the board.

  • fitwizard Mar 01, 2011

    Hi ST13P,
    My dx302 has stopped heating the water, so I tried what you suggested. Voltages all look good on the heater plug (orange/blue wires). 8v when power on. 240v when running. I removed the plug and it is not an open circuit across the contacts. This would indicate the heater element is ok, right?
    I havent pulled the base apart to get at the element yet. I removed the circuit board and had a good look - no burnt/melted joints.
    Any ideas?
    thanks.

  • bdlow Aug 07, 2011

    If you want to try and differentiate between a faulty element or relay: the large "orange and blue" connector has neutral (blue) and the heating element (orange), and is switched via the relay on the control board. 240V across those wires means the relay is off or the track on the board has blown. ~3-4 V across means the relay closed and a reasonable current is flowing (i.e. the relay and PCB tracks have a small resistance); ~0V across would mean no current is flowing and the element is stuffed.

On full cycle when water turned off now not heating water


Hi Barry. Most of the times the problem is the temperature sensor located near to the heating element, at the bottom side of the appliance.

Before going for the sensor check pressure at faucet. Make sure that hot water is correctly connected and that there is pressure. If inlet is double, check water temperature at hot faucet. Test the appliance running hot water for a couple of minutes before starting the cycle.

If that is not the problem, then the heating element and thermostat must be removed from the appliance and tested. Testing is done reading impedance respectively across thermostat and element contacts. If any of the two parts returns Ohms infinity (circuit open), then the part must be replaced. If the parts comprised in the heater assembly are OK test wiring and timer board.

Operations that involve disassembling must be carried by qualified personal.

Dishwasher not heating water already replaced in line heater element no change


Hello

Possible causes;

Incoming Water; Most manufacturers recommend that the water coming into your dishwasher be at least 120 degrees Fahrenheit. If the water is too cold, then your dishes don't clean properly. Or the dishwasher must run longer to heat up the water. Test the water temperature by running the hot water on your faucet for about 2 minutes or until it gets really hot. Place a waterproof thermometer under the water. If the water is too cold, increase the water temperature setting on your water heater.

Thermostat;The thermostat is responsible for regulating the water and drying cycle temperature. If this thermostat isn't working, the heating element at the base of the dishwasher tub may not come on. Test this element by selecting the hottest temperature setting. Run the dishwasher on the shortest cycle. Let the dishwasher run for a few minutes, and open it up. If the dishwasher water is not hot or the drying cycle isn't starting, order a new thermostat from a parts dealer since this component is difficult to fix.

Heating Element/Drying Fan; The heating element heats up the water and air. Access this element by removing the bottom rack. It looks like a long black rod. If any part of this component is broken or corroded, you must order a new one. You usually cannot fix this element. The drying fan is located in the main housing of the dishwasher, and it blows air around your dishes to dry them. Check this part by disconnecting the dishwasher from the power supply and opening up the housing. Examine the fan, and see if any dirt or debris is preventing it from moving. Clean it. If the fan won't turn at all or if the motor is burnt out, order a new fan since it's difficult to repair this part.

If your dishwasher isn't drying your dishes properly, see if you have selected a heated drying cycle. An air drying cycle doesn't completely dry your dishes. Never overload the dishwasher, as this prevents heat from circulating around your dishes, keeping them from drying properly. Plastic and Teflon

Dishlex 302 water not heating


My son fixed this problem with our DX302 dishwasher only this morning. Now works fine and hot. Found the solution on this site posted 11 august 2008 from dishwasher dishlex dx302wb no hot water. There are photos to help you. Take out the circuit board in the top of door and resolder the points on left hand side of green board there are 2 long solders and a half moon. The problem is at the top of the 2 long solder lines. Do not replace your element. There is a fault with the circuit boards on this model 302. I want to thank all the posters for helping me fix my no hot water problem.

The dishlex 302SB is not producing hot water for the washing


I have a Dishlex 302 which had this fault. Initially I thought it was the inline heater element and replaced it. It seemed to work but later no hot water again. Someone here put me on to the problem. There is a dry joint in the control board in the top of the door. This controls the relay which powers up the heater. Unplug it from the mains (very important) and undo the screws around the top of the door (don't take the door right off!) you will be able to wiggle off the front panel containing the electronics. The control board is ealiy disconnected an removed from the machine in its protective plastic cover. Have a look around the PCB and you will see the dry joint. Resolder with rosin core (electronic) solder, reassemble and you should have hot water.

Dishwasher Not Heating!!


Using a multi-meter check for continuity on the heating element, if element is good then check for continuity on the door switch, if this also checks out good then the heater relay located on the control board is likely gone, replace control board.
