undersink water heater for dishwasher?
I like my thirty year old dishwasher but its heater is shot.
How about a dedicated undersink water heater set for extra hot?

Have you searched assiduously for a replacement heater on the interwebs? If you can't find a new one, somebody might just have one on eBay, or perhaps a machine of the same make & vintage that has a working heater. In the past six months I've repaired my dishwasher, microwave oven, washer and dryer, so I've been down this road a few times and might be able to help if you can tell me the details.

a replacement dishwasher is cheaper then a small heater!

especially when you factor in the required wiring.

replace the heater. the heater in a dishwasher heats the water over several minutes so it can use the 1000 w or so available from the circuit for the dishwasher. to do it at the rate the dishwasher fills you'd need probably somewhere in the 5kw range.

You guys have shamed me into pulling machine out and repairing it.
Thanx for advice.

how old is the dishwasher? does it already have like a 3 hour cycle time? if the old one is around 15+ years old you'll probably be sorry that you didn't fix it.

Depends on the dishwasher.
They all seem to flat out suck now, price aside.

I had a bosch for twenty years. Last year I rebuilt it combining two of the same model to end up with one. Not the easiest to dismantle but well made machine.

I would probably go with Bosch. I've heard that Miele is good too but i'd need corroboration on that. I have a bosch that is about 25 years old. I've had to repair or replace the water vavle a couple times and had to install a beefier relay for the heater. Oh and i had to get a slavaged rack because the coating was pretty easily damaged. If I had more space/less stuff i'd probably get a hobart built kitchenaid.

I have a few year old Bosch.
Very very not happy with it. My sister has a top of the line one the same age, she's also not very happy with it.
My dad had a Bosch from 2006 and it seemed much better than these.
If I had to buy a new one right now it would be a Whirlpool and I know even that wouldn't be like the one I had from 2011.

the other issue is that they don't perform nearly as well with post 2011 or so consumer phosphate free detergent.

Interesting.
Does that mean if you have hard water, a water softener is even more beneficial now without phosphates in detergents?

i'm not sure. you can buy phosphate detergent from commercial suppliers. cascade now brands it as "fryer boil out".

There are pros and cons. We got a GE with a steam cycle and other fancy features about nine years ago, and I have to say, that sucker is quiet. I can be standing next to it and not hear it running until it flushes some water down the drain. On the other hand, as I mentioned above, I did have to repair it a few months ago. The control board failed, but it mimicked a power supply problem, so it took some troubleshooting to find the problem, and it was really hard to work on.

I was really impressed when someone at Bosch first showed me one of their dishwashers running almost totally silent. I saw one out in Chicago at the Bosch training center.
Now, that gimmick has worn off at least for me. I don't care how loud it is, I just want clean dishes.
It's wonderful rinsing everything, loading carefully, and still a bunch comes out dirty after 2 1/2 hours. My 2011 Kitchenaid (Whirlpool) you could put filthy plates in it, literally chunks of food, and 99% would come out clean.
It only lasted 10 years, but at least it did it's job. And I think it did it in 60 minutes.

Bosch broke the it can't work if you don't hear it barrier around when I bought mine. Now most of them are designed to be quiet. Also why most of them now have a screen that no one cleans instead of a food grinder so they can make is slightly quieter. My friend has a GE that his landlady bought that is one of their higher end models but also I think one that was made for home depot and it is a terrible machine, it gets nothing clean and usually makes it dirtier than when you put it in.

They showed me the one running back in 2002-03. I assume that's roughly when you bought yours?

Roughly. Somewhere around 99-2000. They had one running in the appliance store in a display. The sales person was really pushing them, I came there to buy a Kitchenaid after they became a whirlpool design. The sales guy actually seemed to be mostly telling the truth, which isn't something I expected at ABC Warehouse.

About thirty years old. Ninety minutes cycle and it works well without heater. I used to repair dishwashers in the days before electronics. Eventually got discouraged because something else seemed to break after I fixed 'em. Probably I'll repair leads to heater if that is the problem. I won't replace element because I doubt that new seal will last. I'm still tempted to connect a plug-in water heater and hope for the best.

you'd need like a 5 or 10 gal office bathroom type of tank heater with a commercial stat that you could set around 160.

If it is the calrod type of heater you can probably reach the terminals to figure out if you need a new heater and grommets or to fix the timer or a thermostat by taking the kick plate off.

We have a Miele. Excellent machine. We're running 2-3 loads a day.

Do you put your head at floor level or tilt the appliance?
0 -
head at floor level, mirror, phone, something like that, unless it is one of those super tall tub dishwashers then you might not be able to get to it without pulling it out. you can use a meter to check the resistance, to check if it is shorted to the metal casing of the heater, and to check for voltage while it is running whenever in the cycle it is supposed to be heating.
