Does a dishwasher have to have metal pipe for water inlet - last installer mangled the nut that attaches line to dishwasher can't get it off

Hello there and thank you for choosing fixya
Most cleaning problems are caused by the dishwasher not getting enough wash water, so the water-inlet valve is often to blame. This valve is usually at the bottom left or right of the dishwasher, behind the lower access panel. It's the device with the main water line from the house, a rubber tube to the dishwasher, and two wires attached to it. When a water-inlet valve is defective, you may hear the sound that's usually referred to as "water hammer." If the water-inlet valve is defective, you need to completely replace it. Dishwasher Water Inlet Valve Replacement

Be sure to read and understand any instructions that come with the new water inlet valve.

Tools required:

Adjustable wrench

Multi-Screwdriver

Pliers

Step 1. Disconnect the dishwasher from its power source.

Note: Dishwashers are usually wired directly to the home's electrical system. To disconnect the power, switch off the circuit breaker or remove the fuse for the electrical circuit the dishwasher is attached to. Try to turn the unit on after disconnecting the power to be sure you were successful.

CAUTION: If you're not sure you've shut off the power properly, DO NOT CONTINUE. Call a qualified appliance repair technician to complete the repair.

Step 2. Turn off the water supply to the dishwasher. This is usually underneath the kitchen sink or in the basement or crawlspace near the location of the dishwasher. Pliers may be helpful here.

Note: If there are no shut-off valves, you must shut the water off at the main water supply valve for your home.

Step 3. Remove the lower panel(s) of the dishwasher. These are usually held by 2 to 4 screws at the upper and lower corners of the panel(s).

The inlet valve is usually near the front of the dishwasher. Attached to the valve you'll see: 2 or 4 wires, the water supply line from the house and the water feed line that goes to the dishwasher.

Step 4. Remove the household water supply line from the valve. The line is usually secured with a brass compression nut. The water supply line is usually copper or braided stainless steel.

CAUTION: Water supply line may be hot.

Step 5. Remove the fitting from the valve the water supply line was attached to. This fitting may be very difficult to remove. It may help to put the valve into a vice in order to remove the fitting. If you cannot remove it, replace it. The fitting is not an appliance part but a plumbing part that is available at most hardware stores.

Step 6. Remove the screws holding the valve to the dishwasher frame.

Step 7. Label the wires to the valve so you'll be sure to reattach them correctly.

Step 8. Remove the wires from the valve.

Step 9. Remove the clamp on the black rubber water discharge tube and pull the tube off of the valve.

Step 10. Reinstall the old fitting (or a replacement fitting if necessary) onto the new valve the water supply line was attached to. Use Teflon tape or pipe joint compound as a thread sealant. Make this fitting tight to prevent leaks. Make sure that the fitting points in the same direction as the old one so that the water supply line will meet up with it properly.

Step 11. Install the new valve in the reverse order of the removal instructions.

Note: The water supply line is under high pressure. Be sure to tighten the fittings properly.

Step 12. Turn on the water to the machine, and check for and correct any leaks.

Step 13. Reinstall the access panel(s). Restore the power to the dishwasher and test.

Note: You may have to let the dishwasher run a few minutes before it reaches the next water fill cycle.

The solenoid valve is under the machine. It will be a block of metal installed with fittings into the water pipe and it has a plastic cylinder attached to it. The cylinder will have two wire terminals on the end opposite the valve block and is typically about 3/4" dia. x 1 1/2" long.

Find out exactly where leak is coming from.
You say water is coming from the side... is that where the pipe connects? Then take apart pipe and reassemble pipe using instructions below, and use rectorseal on joints as described below..
Is water coming from where dishwasher connects to disposal? Then tighten the clamp.
Is water coming from top where disposal connects to sink? Run paper towel around top to check for moisture, and then use steps below to dissemble disposal and re-install same disposal.
Is water coming from a rusted hole in disposal. Then replace disposal using steps below:

Here are the disposal steps:
When I worked apartment maintenance, we replaced disposal with same brand disposal.
That way we didn't have to change out sink basket or change pipes.
How to: Disconnect p-trap and tailpiece going into disposal.
Rotate connector disk clockwise that holds disposal to sink basket.
Before installing new disposal.
Attach electric wire to new disposal.
Attach dishwasher tube to new disposal. Knock out plug inside dishwasher opening.
Push new disposal up into place, and attach to old sink basket with new connector disk.
Use new connector washer.
Re-assemble tubular pipe.



If this is your home, you want new sink basket that comes with new disposal because it looks shiny and new.
Buy a tub of plumbers putty also.
Remove old sink basket and clean opening.
Put finger-size roll of plumbers putty around sink opening, and then push new strainer basket into plumbers putty.
Tighten basket from below, wipe away excess putty around sink opening.
Install new disposal as described above.



Tips for tubular pipes:
When taking apart tubular pipes, start at p-trap and take apart as few pieces as needed to do job.
On image below, loosen both upper and lower nuts, trap falls loose, and then work on disposal.
Any tubular drain pipe that gets moved while working under sink needs to be disassembled, cleaned and re-assembled.
Metal pipes have rubber washer >> always use new rubber washers.
Plastic pipes have plastic washers > plastic washers can be cleaned and re-used.
Plastic washers have flat side that goes toward nut, tapered side away from nut.



When reassembling tubular pipe, we use rectorseal on washers and joints.
Apply good amount on washer just before pushing washer in place and attaching nut.
Rectorseal will ensure tubular drain pipes won't leak.

Hello there
Specific symptoms include: Little or no water enters the tub . To find the cause, first check to be sure the water is ON.

always “zero” the ohmmeter before making any continuity checks on dishwasher components. . When making continuity checks with the volt/ohmmeter, always turn the electricity OFF at the circuit breaker panel. Live voltage checks will damage the meter movement.With the water ON, remove the lower panel. Place a towel or shallow container on floor to absorb water. Loosen the nut that secures the dishwasher water tubing to the inlet port of the water inlet valve. If water collects immediately in the towel or container, it can safely be assumed that the water pressure is adequate and the plumbing system is not clogged . If little or no water collects in the container, the water line gate valve could be defective or there is a problem in the plumbing system.
Turn the water OFF. Remove the lower panel. Loosen and remove nut that attaches water tubing to water inlet valve inlet port. With tubing removed, check for corrosion and debris that has accumulated inside the tubing and inlet valve inlet port. . Turn the water supply ON. Select a cycle on the timer dial where the dishwasher starts to fill with water. If it starts to fill with water — you fixed it. The problem was corrosion inside the water tubing or inlet valve water inlet port. If the dishwasher still does not fill with water, an additional electrical check will have to be made.Next, test for electrical power to the water inlet valve from the dishwasher timer assembly. Using the volt/ohmmeter, set the meter on the 150-volt scale and attach the two test leads of the volt/ohmmeter to the two terminals of the water inlet valve solenoid coil to be checked. Turn the water ON. With the test leads attached to the solenoid terminals, select a cycle on the dishwasher timer dial where the dishwasher starts to fill with water. Push in or pull out the timer dial. You should get a voltage reading of 110-125 volts A/C on the volt/ohmmeter scale. If you get a reading, this would indicate that electricity is available from the dishwasher timer assembly to the water inlet valve.However, the absence of water flow means the water inlet valve is defective

Does it feel free to turn? It's water powered and works in conjunction with the water pump. Do you hear the water/booster pump come on?

if you put clamps on the pipes this sound will stop.you may need to get to the pipes in the wall near the unit,also you maybe overloading the unit if water remains in unit.try less and see what happens.

Do your dishes look cloudy or spotty? If so it is not soap but rather hard water residue. Go to www.dishwasherfilter.com and get a filter that filters the water before it enters your dishwasher. it is very affordable(like 70 bucks) and guaranteed to work or you can return it for a full refund. I bet this will solve the problem.

Simple......the new disposal has an inlet pipe that the dishwasher drain hose attaches to. But remember...YOU MUST KNOCK OUT THE PLUG in the inlet pipe or the dishwasher water just backs up into the dishwasher.
