Is there a door lock on a Jet Tech F-18 dishwasher? Our church hasn't known how to use ours for several years and the door won't open.

Video at the link below suggests it may have a locking feature:

It depends on how old is the machine. the more recent unit (5 years) used door guide (green) #16468. Search by part number or description

Hi -

The issue may lie with the door latch; a door switch is used to start and stop your dishwasher. It's a safety feature that won't allow water to flow with the door open. With a faulty door switch, there is a chance your dishwasher won't start at all. Dishwasher door switches are about an inch long. They are usually black but can be red. There are metal prongs on the body of the switch called terminals. Some door switches have two terminals and some have three. If your door switch is OK, check the timer assembly. This controls when and how long power is sent to other controls on your dishwasher. If these controls don't receive power, they won't work. The timer assembly contains a motor. Check this motor as well. It is often cheaper just to replace the timer motor rather than the complete assembly. My last suggestion is to check the cycle selector switches. These switches indicate cycles for washing, drying, and setting the temperature of the water. If one of your switches is the problem your dishwasher may not start. Dishwasher cycle selector switches tell the timer which cycle to run by opening and closing electrical circuits. Most selector switches are six to eight inches long. They are usually black and have terminals. By testing each one of these parts with an ohmmeter you should be able to determine why your dishwasher is not working. It is possible for other parts to fail but these are the most common parts to check. If any proves to be ineffective, I strongly suggest contacting a professional to move forward accurately.

If your dishwasher door won't lock, it could be a problem with the latch adjustment or the door seal. Some latches are designed to be adjustable, and yours may be set too tightly. Look at the owner's manual for specific instructions or follow these basic steps for adjusting the latch:

1. Spray WD-40 or other lubricant onto the latch.
2. Slowly open and close the door several times, noticing whether the door hits the strike plate (the metal plate on the top of the dishwasher frame). Use a hammer to lightly tap the strike plate to move it as needed.
3. If possible, adjust the depth of your latch by unscrewing the latch assembly using a screwdriver and reseating it. Work with the adjustment until it latches correctly.
Note: If your latch is permanently fixed, have a qualified professional address the problem.

The door seal-also called a gasket-can also cause problems if you have a brand new dishwasher or door seal. The good news is that the door seal will mold to the door's shape over the first week or so. Operating your dishwasher with the highest level of heat will help this process happen more quickly. Because the material is pliable, and because heat will soften it, it will seal to the door more securely after those first few loads.

On the flip side, an old door seal can also keep your door from closing correctly. Check the seal for signs of warping or damage. If the seal needs replacing, arrange for service, or consider doing it yourself. In most models, it's a relatively easy DIY project. See Dishwasher gasket replacement for step-by-step instructions.

Yes. They are available. often including the microswitch not too expensive.

The door switch, by door hinge, resets the timer for the next cycle. The door needs to stay open for about 8 seconds to complete the reset.

There is also a switch inside the door at the handle. This can cause a similar syptom. (The light cycles, but the unit won't start)

If the door switchs are working proper, you may need a new timer.
