The short answer
When the door of a Criterion dishwasher stops sealing, look along the seal for hardening and along the latch for wear. Both are visible with the door open and neither needs the machine moved. Read the near-miss line in the symptoms first if you are not sure you are on the right page.
Signs, including the misleading ones
- Steam escaping around the door during the cycle — The seal is no longer making contact, and the steam is reaching the fascia above it. If this is what you have, you are on the right page; if not, follow the near-miss line.
- Water running down the inside of the door at the end — Normal condensation in small amounts; a stream means the seal is failing to hold it in. Doing it in this order is what keeps the diagnosis short.
- A hardened, flattened or split seal — Heat cycles stiffen the rubber until it stops sealing, and the split is usually along a fold.
- The door drops or feels heavy on its hinge — Hinge springs and cables wear, and a door that falls open no longer closes squarely. It is the sort of check a technician does first, for the same reason.
The ranking
- A worn latch or misaligned striker — Second because the latch is what pulls the door tight, and a loose door cannot seal however good the rubber is. This is the cause people skip, and skipping it is why the diagnosis takes three visits.
- Debris in the seal channel — Food and detergent residue in the channel hold the seal off its face, which is free to correct. If this is what you have, you are on the right page; if not, follow the near-miss line.
- Worn hinge springs or cables — A door that has lost its balance drops and closes crookedly, so the seal contacts unevenly. The position matters more than the name: work the order rather than the one you have heard of.
- Overfilling or excess suds pushing water to the door — Last, because the door is innocent: water is being pushed past a seal that is doing its job. Compare it with how the machine behaved a month ago rather than with how you expect it to behave.
Where to start, and why there
- Feel the seal for hardness and look for splits — A seal that has lost its give no longer seals, whatever it looks like. Repeat it once if the answer is ambiguous rather than moving on with a maybe.
- Close the door slowly and listen for the latch — A soft or absent click means the latch is not pulling the door tight. Eliminate it properly before moving down; a half-checked cause comes back later.
- Clean the seal channel and try again — Debris in the channel is a free fix and it accounts for a surprising share of door leaks. If the answer is clear, stop here and act on it.
What to try before calling anyone
- Wipe the striker and the latch face — Detergent residue on the striker stops the latch seating fully, which loosens the door seal. If it does not change anything, that result is still worth recording.

- Check and tighten the visible hinge and striker fasteners — Snug them and then close the door to confirm it meets the tub squarely. It is the sort of check a technician does first, for the same reason.

- Reduce the detergent dose for the next few cycles — Excess suds push water past a good seal, and the dose is free to change. Leave the machine a few minutes afterwards before you decide it has not helped.

What has to be off
Safety
Unplug the machine or switch off its breaker before any panel comes off. Treat the wiring as live until you have proved otherwise, whatever the switch says. Heating elements stay hot long after a cycle ends, so give the tub time before your hand goes near the bottom of it. Nothing here asks you to interfere with a switch that senses the door, and nothing should.
When to call a technician
The line is simple enough to state: you own the cleaning and the adjustment; a technician owns the parts. Crossing it costs more than the visit would have. Do not keep running the machine to see whether it clears; every cycle after a leak starts pushes water further into the floor.
