I need to replace the drain hose on my Samsung dishwasher as old one split but cant work out how to do it.


It's a big job. You have to pull the dishwasher all the way out. On most Samsung DW's, you then need to remove the metal panel on the left side of the DW to be able to get to the case-brake assembly. Remove the water inlet port on the inside of the dishwahser by turning it counter-clockwise ( a tool will be required). Pull the case-break assembly out so you can get to the clamp that holds the drain hose in place. Pull the clamp down and remove the hose. Have a towel or Sham-Wow ready to catch all the water. You will have to disengage the hose clamp at the back of the dishwasher, then you can pull the hose out. Reverse the process to install the new hose. As I said, it's a big job; if it sounds like more than you want to do, I recommend calling a professional repairman. Sears has technicians who are experienced with Samsung dishwashers.

I WANT TO REPLACE DRAIN HOSE WITH NEW ONE AS OLD ONE SPLIT


It's a fairly big job. You have to pull the dishwasher out from under the cabinet. Then remove the left-hand metal panel. You should now be looking at the case-brake assembly. Reach inside the dishwahsher and turn the water-inlet bezel counter-clockwise to remove it. Now you can tilt out the case-brake assembly and loosen the clamp that holds the drain hose in place. Pull the hose off (have a towel or Sham-Wow ready to catch the water). Then you have to remove the clamp or hose-restraint at the back of the dishwasher. Thaen you can pull the drain hose out and replace it.

Diplomat ADP8322 Does not appear to load sufficient water thereby spray arms not rotaing


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.

We have removed our dishwasher, we are not replacing it. The question I have is...."How do you cap of or plug up the old waterline that goes to the dishwasher?"


It all depends on what material your water line is made of and where you want to shut the water off at.

Under the dishwasher there is a threaded connection from the water line to the dishwasher and there is typically no isolation valve located there. You will have to follow the supply line back to where it ties in, typically it is feed from the kitchen sink water supply. Hopefully the plumber who installed the lines provided a local shut off valve under the sink, otherwise you will have to shut the water off at the main house supply.

Here is a couple of ways to cap the line off.

Copper - You can get a cap and solder it on, make sure there is no water in the line because it will not heat up enough for the solder to penetrate the joint. Use flux and lead free solder on the copper lines. When you are ready to replace, just turn the water off, cut the cap off, and install the necessary fittings to connect the dishwasher. If I was going to do this, I would install a valve and a braided stainless steel line for the dishwasher. This makes it a snap to reinstall. Any hardware store can supply these parts.

Plastic (PVC/CPCV) - same as above but use the proper cement rated for the type of plastic pipe.

PEX - You can buy a plug and a clamp ring, but you will need the proper crimping tool.

If you have a threaded connection, just go to the hardware store and buy a threaded cap.

If you need specific information, please update your question with more details, because I am just speculating what you have.

Whirlpool dishwasher Leaking water


Hello there:
Troubleshooting Leaks
If the dishwasher leaks, and you know the problem is not related to tub overfilling, the pump, or inlet valve problems, the plumbing connections may be faulty. Most dishwashers are connected to the water supply with metal pipe fittings, and the leak could be at these fittings. If the fittings are threaded, tighten them with an adjustable wrench. If this doesn't work, chances are the threads are stripped or the fitting is cracked or otherwise damaged. In this case, replace the fitting.
Most dishwashers discharge used water through a pipe or a hose connected to the drain or garbage disposer under the kitchen sink. If the drain line is made of flexible hosing, it may have cracked from prolonged exposure to hot water. Examine the hose; if it's damaged, replace it. If the hose is leaking at its connections with the disposer or dishwasher, tighten the fittings or clamps at the connections, or replace the clamps. Also check for water leaks around inlet valves, drain valves, and anywhere you see flexible hoses and hose connections. Leaks at clamps can be stopped by tightening or replacing the clamps. Leaks in hoses can be eliminated by replacing the hoses.
I HOPE THAT YOU FIND THIS INFORMATION VERY HELPFUL

Mdb7100aww maytag, just not draining now. never problems before. water standing in tub and shuts down????? Float appears to be functioning just does not seem to drain, possibly drain motor?


Elimination Of Problems From Most To Least Likely:

1. Connection from discharge hose to drain pipe is blocked/corroded.
a) Loosen the gear clamp (5/16" Nut Driver/Phillips/Standard) holding the discharge hose to the barbed drain fitting.
b) Check that the barbed fitting is not blocked by poking at the opening wth a screwdriver.
c) If the barbed connection is Galvanzied and it has gotten heavily corroded, replacement of that fitting is recommended.

2. Discharge hose is blocked/kinked from dishwasher to drain connection.
a) After 1b), place discharge end of hose into a bucket and run the dishwasher through a cycle.
b) If flow is poor, examine hose for kinking or parts (such as couplings) that may have corroded shut. Removing front panel and using a flashlight will be required for this (1/4" nut driver/phillips) If such corrosion found, 1c).
c) If hose and fittings are ok, there may be an inline filter whose screen is clogged or a filter screen where the dishwasher ties into it's discharge line.
3. Pump has failedinternally . Usually held in place by large squeeze clamps, screws, gear clamps. Will most likely removal of dishwasher from alcove to repair. Any reputable dealer should stock parts. i.e. Kenmore => Sears
N.B. May be under warranty - check. May be cheaper just to get another dishwasher at this point, especially if the dishwasher is more than 10 years old.

Dishwasher holds water


if you dishwasher holds water that means the plumbing connections may be faulty. Most dishwashers are connected to the water supply with metal pipe fittings, and the leak could be at these fittings. If the fittings are threaded, tighten them with an adjustable wrench. If this doesn't work, chances are the threads are stripped or the fitting is cracked or otherwise damaged. In this case, replace the fitting.

Most dishwashers discharge used water through a pipe or a hose connected to the drain or garbage disposer under the kitchen sink. If the drain line is made of flexible hosing, it may have cracked from prolonged exposure to hot water. Examine the hose; if it's damaged, replace it. If the hose is leaking at its connections with the disposer or dishwasher, tighten the fittings or clamps at the connections, or replace the clamps. Also check for water leaks around inlet valves, drain valves, and anywhere you see flexible hoses and hose connections. Leaks at clamps can be stopped by tightening or replacing the clamps. Leaks in hoses can be eliminated by replacing the hoses.
also it may be due to faulty pump
Servicing the Water Pump

In most dishwashers, the water pump is located under the lower sprayer arm. This component pumps the water through the dishwasher. The pump has two impellers, top and bottom. These, as well as other components, can become clogged with food or detergent. Here's how to disassemble the pump:

Step 1: Remove the cap that holds the sprayer arm on.

Step 2: Remove the sprayer arm, the screen, the pump housing, a bolt, the upper impeller, the food disposer blade, a spacer plate, the impeller hood, a flat plate, an O-ring, and the lower impeller. Lay the parts out in order as you disassemble them so that you'll be able to reassemble them properly.

Step 3: Clean the parts thoroughly with a mild detergent solution. If any parts are worn, replace them with new ones made for the dishwasher.

Step 4: Replace any seals, such as the O-ring or other washers, with new ones.

Step 5: Reassemble the pump, keeping the parts in order.

To reach the water pump, remove the sprayer arm and screen and then the pump housing. Remove the bolt, and the pump components can be disassembled.

On some dishwashers, the lower impeller serves as a drain pump. This type of system usually has a reversible motor; machines with nonreversible motors have drain valves, as detailed previously. If your machine possesses this impeller pump system, and the water will not drain from the dishwasher, clean the lower pump impeller. This may solve the problem. Otherwise, call a professional service person.
