Is there a way to adjust the pressure on a dishwasher?

You do not need to call a repairman to solve this. With a few home tools, you can change the pressure switch, which governs how much nozzle pressure comes from the dishwasher jets, and you'll be enjoying gleaming dishes in no time. Turn off the water and power. Remove the access panel on the bottom of the dishwasher (if it has one). You will need a small flat-head screwdriver to take out the four screws that hold the panel on.

The switch itself is located inside the casing next to the control panel. It can be replaced by taking the dishwasher apart; just make sure that you buy one that matches the type of dishwasher you have. The switch costs about $5.

If your dishes are still not clean, it may be because of clogged filters. A dirty filter prevents hot water from flowing through the system and allows debris to build up in the pipes. This causes the heater element in the pump to fail first before other parts of the system. This can happen quickly, so be sure to check your filters regularly for clogs.

How do you reset a dishwasher?

To reset a dishwasher, press and hold the start button for three seconds, or, failing that, turn off the main power supply. If it does not resolve the issue, you may have difficulties with your power, water supply, door lock, or internal issues. You should call a professional repair person to come out to your home.

If you try these steps and it still won't work, let us know so we can help identify the problem.

How is the dishwasher connected to the plumbing system?

A drain line connects the dishwasher to the plumbing system. Locate the dishwasher's rubber hose and follow it to the final connector. It may be slanted upward to connect to an air gap fitting installed on the sink or countertop. If this is the case, release the clip or clamp that is securing it to the air gap and disconnect the hose. Then pull it out from between the sink and countertop.

If the hose goes into the wall, it will be attached to a threaded hole filled with a washer and nut. Attach the end of the hose to these items and turn it slowly to tighten it up. Make sure that you do not over-tighten it, as this could cause leaks or damage to the wall.

The dishwasher's water supply pipe attaches to the kitchen faucet. This is usually done with a flexible tube called a riser pipe. It runs from the supply pipe at the floor to the faucet mounted above the dishwasher in the countertop. The riser should be about 1/2" diameter for best performance. Large holes in the supply pipe allow water to reach the dishwasher even if the main faucet is turned off. Smaller holes are needed if you plan to use low-flow fixtures.

Before you start working on your dishwasher, turn off the gas valve at the kitchen faucet and let the water run until it stops. This will remove any gas that might have leaked from the pipes or connection points.
