Dishwashers

Normally you will install a dishwasher drain pipe above your kitchen sink drain, so you are using the sinks P-Trap. When installed in this fashion, no you don't require a seperate. If you want to install your drain elsewhere, than yes you need a trap otherwise you will have sewer gases backing up through your dishwasher and into your kitfchen

On purchasing my own Contessa china "Dishwasher Safe" was an important element - this was the case, so yes.

bleach, dishwasher soap, detergent, soap bars

at aprox. 500 degrees f

So far they are, but soon will be made in China.

No, if it's not safe it may melt, then you will have real problems.

the first ones are wooden .

What does that have to do with dishwashers.

The first reports of a mechanical dishwashing device are of an 1850 patent by Joel Houghton of a hand-powered device. Modern dishwashers though, come from an invention in 1886 by Josephine Cochrane.

Possibly if the housing is big enough.

About 10 for a regular wash.

Simple answer: Yes, the same way you stop a microwave or a dryer. I don't know why some people stress out about it so much, it doesn't make sense!

By the way I am a plumber and I fix dishwashers all the time...been doing it for over 10 years

You don't. Wood cannot withstand the extreme temperatures, water, enzymes, and bleach in a dishwasher. While a wood utensil or dish may tolerate the dishwasher, its lifespan will be far shorter than if it were hand-washed in the sink. And, the wooden item may very well become misshapen or "furry" (when the fibers break and bend, resulting in the fibers sticking out from the body of the piece).

I'd say you might have food stuck in the drain hose.. If that's not the case, maybe there's been a Lyme build up and it needs cleaned.. Check for hose kinks too.. Or even make sure the machine is level.. Just my opinion...

The pump in the dishwasher should keep the water from getting into it.

Possibly at your local appliance parts store, or online.

You have a problem with the pump, or a blockage in the drain.

Food is stuck in your drain. There is something at the store u can buy and pour down the drain to clear it up

hydrodynamic principle for cleaning

electromechanical timers/ computerized digital timers for each cycle operation of cleaning

The sink drain is plugged,or you have the dishwasher hose hooked up in wrong place.

Run your dishwasher with jet dry or a dishwasher cleaning product with nothing in it.

Possibly at your local appliance parts store, or online.

Fit a short length of capped hose to the disoposal fixture.

Take out and clean the filter from bottom, possibly also the pump.
