Question about Bosch SHU5316UC Dishwasher
Ran the test suggested for error code f and get code 4. I'm still not sure what that means and how to actually fix it. Any assistance would be greatly appreciated. Thanks!
Sounds like you may have put it together wrong. I would just take the arm back off and make sure that it all fits together right. A little tip for you too. Dishwashers will clog up all the time with water deposits and food gunk. There are all those expensive cleaners out on the market but the best and cheapest way to clean them is with white vinegar. Simply pour it into the dishwasher when it is empty and run it on the pots and pans setting on hot. Always make sure to pre heat your water too by running the sink till it starts steaming. This will make it easier for your dishwasher to heat the water. If you don't, then when you turn on the dishwasher it starts to fill with cold water and has to heat it on its own. Run the vinegar though through it at least once a month or so and it will extend the life of the dishwasher. Hope this helps. Just try taking that arm back off though and putting it back together making sure everything is fitting properly. If you have any other questions feel free to ask me. Good luck.

How to Check the Spray Arms
Home > How To > Appliance > Dishwasher >Check
Caution: Please read our safety information before attempting any testing or repairs.
The pump/motor assembly pumps water up through the spray arms. The force of the water cause the arms to spin and spray the water and detergent mixture into the dish and glass racks. Some dishwashers have just one spray arm at the bottom in the tub, others have a second spray arm under or over the glass rack. Some dishwashers also have a spray tower that rises up out of the lower spray arm to concentrate an additional blast of water.
To access the bottom spray arm, remove the bottom dish rack. Reach in and spin the spray arms. They should spin freely. Lift up the spray arm from the end. There should some play in the arm allowing you to wobble it up and down. Inspect the seams of the arms for splits. If water sprays out of a seam, the dishes will not receive an adequate spray for proper cleansing and the force of the water directed at the door may cause leakage.
The lower spray arm may also have a spray tower. If it does, pull up the center part of it as far as it will extend and let it drop. It should lift and drop smoothly. You can also unscrew the tower by hand to inspect the interior for foreign objects that might clog it.
Remove the upper glass rack as necessary to access the upper spray arm. Repeat the steps above for the lower spray arm. The upper arm may not have as much wobble as the lower arm.
The water source for upper spray arm on some dishwashers may be through a tube which mates with the spray arm when the rack is pushed all the way back. Make sure that the rack is properly aligned with the water supply tube.
If necessary, the spray arm can be removed for cleaning or replacement. Unscrew the spray tower (if any) by hand and remove the bolt (if any) in the center of the spray arm. Otherwise lift and rock the spray arm until it comes off. Keep any washers in the same order as they are removed. To clean, soak it in warm water and rinse with a vigorous spray.

An error 24 code on your Bosch dishwasher means that you have a clog or that your pump is bad. Check and clean out your airgap. If that doesn’t work and your machine is still under warranty, call Bosch. Bosch won’t tell you what the error code means, only that you need a service call, and they will then give you some phone numbers for Bosch authorized appliance repair places, one of which was Mr. Appliance. The appliance repair place will want to put in a new part whether you need it or not so that they can get paid by Bosch. I found this out the hard way. Hey Bosch, be smart and tell your customers what the error codes mean so that they are informed and you don’t look like you are trying to rip them off. Leave that to Mr. Appliance. You can always remind the customer that working on the actual dishwasher voids the warranty. It doesn’t take a rocket scientist to figure out how to clean out the airgap, which isn’t a part of the dishwasher, but rather part of your plumbing connected to the dishwasher. I suspected this to begin with, but because you told me I needed a service call, I had to assume it was beyond basic owner maintenance. Great way for you to flush money down the toilet and look bad doing so.

Thank you for your inquiry, Elizabeth!
I see that your Frigidaire dishwasher is displaying an error code of "UL" and you would like to know what it means. A "UL" error code means that your dishwasher is in relay test mode. You should be able to clear out the error code by pressing cancel and holding down the hi-temp button. If that does not clear out your error code I would suggest performing a reset on your dishwasher and you can do that by flipping the household circuit breaker off for at least ten minutes. Hopefully this information is helpful. -Matt
