Fisher and Paykel top dishwasher is showing F3 damage after a short circuit we had. How do I fix?

This is serious. The thermostat is not working thereby causing the heater to overheat and the protection circuit cuts in. The only way to replace thermostat is to replace the whole heater element as the unit is fully integrated. Will need technician to replace the heater element unit as it is very complex assembly.

Fast and delicate lights flashing on Hotpoint fdw60

Them 2 lights flashing indecates a heating fault.

For this you will bee to pull machine out and remove the side panels. From there locate the heater and with a multimeter check to see if the heaters open circuit. If so you will need to replace the heater element. If the heaters fine then on some models theres a thermostat next to the heater. Check this aswell if fitted

I have a Bosch Classixx slimline dishwasher. I completes most of the cylcle but trips out the electricsnear the end of the cycle - probably the drying cycle - any ideas Garry

Hello Garry,

I suspect the element in the water heater is either burning out or shorting to earth. If it's burning out, the increased resistance will cause an overload and trip the breaker or blow the fuse for that circuit. If it's shorting to earth, it may trip both the breaker and the RCD in your fuse box / consumer unit.

Next time it happens, check whether the RCD switch (assuming you have one) is in the 'OFF' position. Most breaker boxes will be fitted with an RCD which protects many, or all, of the individual circuits. It's easily identified by the presence of a 'TEST' button.

That's only going to be a clue to the likely cause of the fault though. You really need to do some testing of the element with an ammeter and/or multi-meter, if you have one. I can provide instructions for testing if you have the equipment and inclination.

Unfortunately, if it is the water heater, the cost of a replacement is about £100 for the part alone, for the SGS43C12. Water heaters for most other Bosch models are roughly the same price and some of the older models can be £130+. If you need to get someone in to fit it, you could be looking at a total bill of between £150-200. Considering the age of the SGS43C12 / Classixx, it may be time to consider replacing the dishwasher.

Obviously, I'm assuming it's the water heater as this is the most likely cause, but there are other possible faults. If you need any instructions on testing, etc, please confirm the correct model number as the SGS43C12 isn't a slimline model.

Hope this helps. Please let me know if I can be of further assistance.

I have a LG LD-14AW2 dish washer. it starts and then displays "HE". Is it the heater unit?

Hi glen bundese,

Yes it is the heater unit...

HE means Heating Error - The Element needs to be replaced - Or the Thermistor on it, though if the thermistor was faulty it would give a TE error.

Both parts come as a unit (Usually). I would refer you to a qualified L.G technician in your area
- Replace the element unit, and things would be OK.

Kind Regards :-)

Do you have any idea what the problem would be if the dishwasher fails to stop, The digital dial counts down down until 1 and then never drains or switches off, just keeps on going

Hi there,

The "1" is actually an error code indicating a fault in the water heating circuits. The endless cycle means the water isn't reaching the desired temperature or, in some cases, the controller isn't receiving the correct signal to indicate the water has reached the correct temperature. If the water doesn't reach the desired temperature, the wash cycle wont advance and the "1" will be displayed.

This is usually due to a failing (or failed) water heater or a fault in the control module. Often, one of the pins for the heater relay has burned out on the PCB causing a dry joint. This can sometimes be re-soldered. Occasionally, it can also be a fault with the NTC water temperature sensor (Negative Temperatire Co-effecient), but this is less common.

There are some simple tests you can do without any disassembly or electrical testing.

- If you have an RCD (residual current detector) fitted locally to the dishwasher or in your fuse box / consumer unit, a failing or failed water heater would usually trip this. If an RCD is fitted and is not being tripped, I would start with a visual examination of the solder joints for the heater relay on the control module

- Check whether the water is getting hot. Start a quick wash cycle and leave it to run for about 10-15 minutes. Then open the door and check for the presence of steam and/or test the water in the bottom of the washer by hand. It should be hot, not luke-warm.

These are only simple checks to determine the best place to start looking for the fault. You will still need to do some further testing to find the exact cause of the fault. This will require some dis-assembly of the dishwasher and you will also need a Torx T20 screwdriver and a multi-meter for electrical testing of the water heater.

If you have these tools and would like to try fixing this yourself, please let me know. If you are in the UK, the control module and water heater are about £100 each to replace, so you should take into account of the age of the washer before replacing these. The control module can be replaced fairly easily on a DIY basis, however the water heater and NTC are significantly more difficult and may be best left to a professional service engineer.

If you need further assistance. Please could you also confirm the correct model number of the dishwasher (I don't recall the SGS43C12 having a digital time display) and whether you are on a 120 or 220-240 volt supply.

Hope this helps.

Whirlpool DU943 leaks heavily when filling from

I doubt the H2O tank temp would have any affect... to fix the problem you will need to pull the unit out and replace the supply line from the valve to the elbow... I would recommend braided line.

If your talking about the fill tube that loops up the side of the unit it usually is just seperated at one of the fittings and can be pushed back intp lace or recalmped... otherwise you will have to purchase a new oem tube.

Replacing the heater unit in a Bosch dishwasher SGS43e02

I have just finished changing the heater on my Bosch SGS55C02GB. It is a tricky job but fixed my problem for £100 instead of paying £350 to replace the whole thing. My model had no access hatch to the heater, as described by the previous solution, the only way to get to it was to take the whole plastic bottom off the unit. After reading other posts on other forums, taking the bottom off seemed like a nightmare job, so instead, I cut out a hole in the plastic tray with a jigsaw and created my own access. Obviously had to be vary careful not to cut any wires or pipes! This allowed me to actually get to the screws to undo them, and swap the heater for the new one. The only extra part I needed was a new jubilee club to replace the original one that attaches to the pump. The part I replaced was:
Good luck!

LG Dishwasher LDF6810ST

As I had the same problem, I worked on my machine and found out the heater unit was not working (it is a brand new machine ! - remark : as I moved overseas, LG did not cover it with their warranty).
But back to what I did : I ran the check program (instructions can be found in the Service Manual) and verified it was sending voltage to the heater on step 36. So I checked the heater unit (in the bottom of the machine) and found it was burned or open. So I ordered a new heater assembly ($40 on eBay), replaced it myself and am completely happy with the results.
Remarks : the heater is powerful enough to heat cold water to the temperatures required (I don't have hot water in the faucet); it seems that the heater also produces heat for the drying cycle (my dishes were completely wet at the end of the cycle before, now they get completely dry). My only disappointment, mentioned by some in the forum, is that the outlet during the drying cycle is in the bottom of the door, so steam condensates into droplets on the kitchen floor. But now I get clean dishes, and this machine is amazingly silent and efficient. Good luck to you !

Vented vs. non-vented dispenser unit

If you cannot get a non-vented unit, just buy the vent fitting that fits onto the dispenser runs accross the door panel and down the door to the gutter in the bottom of the door. There should be no problem using the unit "as-is", but if you see small amounts of water dripping from below the outer door panel, get the vent tube. It should be inexpensive. Oshie
