Question about Bosch 24 in. SHV4303 Built-in Dishwasher

1 Answer

The upper arm no longer turns. It is 11 years old. It is SHV 4303 from 2000. If it can't be fixed will the panel fit any current dishwasher, whether Bosch or not? How noisy was it rated to be so I can compare to newer models?

Neff dishwasher - bottom tray not cleaning - rotary arm not turning


If your dishwasher is 10 years old and you are facing a significant repair cost, it may be time to consider replacement.

Top spray arm not turning


Water-inlet valve
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.
Internal filters
Every dishwasher has some type of filter to keep large food particles and foreign objects away from the pump assembly:
Most modern dishwashers have self-cleaning filters that don't need any routine cleaning.
Some have filters in the bottom of the dishwasher that you need to periodically clean. You don't need any tools to remove the filter, and cleaning it is easy. Consult your owner's manual to determine which type you have and its maintenance requirements.
If your filter is clogged, it may be causing the cleaning problem.
Drain valve
Some dishwashers have a valve (or gate) that should open only during draining. If debris lodges in the valve, it can't close properly, so water drains out during the wash cycle. Most dishwashers drain into the garbage disposer. If yours does that, listen for water flowing into the disposer during the wash cycle. If you can hear it then, the drain valve may be clogged.
Spray arms
There's a spray arm at the bottom of your dishwasher--it may have a tall spray tube mounted to the center of it. There may also be a spray arm located directly beneath the upper rack of dishes and/or above the upper rack.
If debris is blocking the holes in the spray arms where the water comes out, it could cause cleaning problems. Regularly inspect each of the spray arms and clean out the holes as necessary.

I have just moved into a new house with what looks like quite an old ADG7540 dishwasher. The detergent dispenser doesn't open during the cycle - even though I have cleaned it. There also doesn't appear to...


Hi jo..... many of the old dishwashers did not have an upper arm. Regarding the detergent dispenser there are a couple of reasons why it no longer operates but rather than spend money on a repair I recommend that you simply purchase the 3 in 1 tablets and toss one right into the floor of the dishwasher and turn it on. That said, always run the hot tap water into the kitchen sink until it is as hot as it will get BEFORE turning on your dishwasher.

AND since this is an older model always rinse any food or debris from the dishes before placing them into the machine. Joe

Thanks for choosing Fixya!

Apparently no water pressure to upper washing arm.


Hi sounds like there is a blockage in the circulation pump which causes low water pressure as it cannot push the water around. You would have to remove the unit and turn on it's side and remove the circulation pump to clear the blockage.

Also check all the holes in your spray arms for any blockages. Best to remove each arm and clean in the sink. Any blockages causes the arms not to turn.

Upper spray arm failure


Easy to solve!
(1) Remove the drawers to give yourself room to work
(a) bottom drawer just comes right out -- but you knew that
(b) Carefully unclip small plastic retainer caps at the ends of the metal "glides" for the top drawer. Then slide the caps out of the glides. Then remove the top drawer.
(2) Unscrew the "gear-like" plastic fitting into whose hole you were sticking your finger when you felt that small cylindrical ring.
(3) Now that you've got access to the ring, the solution is obvious -- use it to snap the upper arm back into the gear-like fitting. When you're done, the arm will rotate freely in the fitting.
(4) Put everything back together and enjoy the fact that you didn't have to pay some yobbo $75 to come to your hous and do this for you!

(HINT: When screwing the gear-like fitting back into place, use the old machinist's trick of pressing gently and screwing backwards until you feel a click. The threads will now be aligned for you to screw things together the right way. If you do not do this, you might experience frustration reattaching fitting -- since the piece it screws onto is spring loaded.)

Upper spray arm doesn't move. Replaced inlet


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?

Upper spray arm on dishwasher does not move


you most likely have gunk inside the arm or holes not allowing the water to spray out and turn the arm. Otherwise, the arm bearing may be stuck and will need a gentle push to loosen up.

Maytag MBDF550Aww upper spray arm doesn't spin.


Cleaning the filter was the right thing to try.
Since you don't see cracks/breaks on the spray arm and it appears that it is spinning freely, I doubt that replacing the spray arm will fix your problem.
If your dishwasher is several years old, your problem is likely a failing pump motor, but before you swap that out, check that the impeller is not damaged. Good Luck!

Dig deeper, until you find filters. Those are probably clogged. You may need a screwdriver...
