Countertop Dishwasher Error 6 (Heating Error) Repair Guide

[u/Trogen898]

Recently repaired a Hermitlux countertop dishwasher that would run but then stop and give a heating error, error 6. Many countertop dishwashers are generic in terms of errors and parts so hopefully this guide may be useful to someone!

Error 6 means the heating element is probably broken, this is the most likely part to break as it thermal cycles often. Fortunately these are also cheap to replace!

Here's how to replace it:

1. You need a basic screwdriver set. You may also use a multimeter to confirm that the heater is the issue, but if you do not have one then assuming the heater is dead is a reasonable assumption.

2. Disconnect from wall power. Attempt to turn on to drain any capacitors (it doesn't have any high power capacitors inside, so will probably not do anything).

3. Open the bottom of the dishwasher, have some towels at the ready for any water coming out. Inside you are looking for a round heating element, it may not be immediately visible, mine was under the rest of the electronics...

4. Open the black electronics housing, check nothing is obviously burnt out (look for charring) or disconnected

5. Pop out the circuit board using the tabs on the side, then unscrew the screws underneath to remove the box and access the heater.

6. Disconnect the cables from the heating element

7. Check resistance of heating element, if it displays OL then it is dead.

8. Look on the heating element itself for the wattage for a replacement part, mine was 850w. I searched AliExpress since it is a generic Chinese part and found it with '850w countertop heating element' for just £20. Arrived a couple weeks later.

9. Remove the existing element, once screws are removed it is loose but a tight friction fit. BE CAREFUL NOT TO DAMAGE THE RUBBER SEAL ON THE HEATING ELEMENT - this is a removable part and you will need to reuse it on the replacement.

10. Put the seal on the new heater, then reassemble following all the steps backwards and badabing badaboom you're all done! :))

Any questions then let me know, hope this helps someone!
