Philips Whirlpool Integrated Dishwasher

Model numbers that are worn or missing are hard to find. When you go to whirlpool's website you might find your dishwasher there, other wise it might not have them listed because it is obsolete.

One place to look is on the panel below your dishwasher door. In some cases it is stuck there, or somewhere else under the dishwasher.
I have seen them inside of the dishwasher housing (under the cabinet between cabinet and dishwasher.

Very rarely will you find the model numbers inside of the dishwasher doors. However according to Whirlpool, if you open your door, you will find a sticker or a riveted plate on the right hand side of the dishwasher's frame, near the seals.

One thing I suggest however once you have discovered the model number, write it down and put it someplace safe.

Good luck
