Hello and Happy New Year! My b/f has a Maytag dishwasher model MDB4949SDH0
The top rack does not clean dishes. S/N F45123047 We think the unit is approx. 7 years old. I tried all of the cycles Power Blast Auto Normal and Quick. All give the same result. Dirty dishes on the top rack at the end of the cycle. I ran a cycle adding vinegar and baking soda after the machine started. I also tried a vinegar mixture and letting it soak. No difference. When the door is opened during the cycle I see the upper arm coast to a stop so I know it is getting water. The holes in the upper wash arm are not clogged. I see YouTube videos of people disassembling the filter mechanism under the lower wash arm and thoroughly cleaning several parts in order to correct this type of problem which according to the video was a KitchenAid version of this dishwasher. I will run the machine again with cups/ glasses right side up in the top rack to see if they fill up with water during the cycle. I searched for this issue on this site and did not find others with this problem. All of the dishwashers at my house are vintage and have no issues cleaning dishes. I've read good things about KA and Maytag dishwashers by Whirlpool. I may purchase one myself one day but for now would like to get this one to work properly. Thank you, | ||

Poor top rack cleaning
Hi Michael, how bad do things look coming out? What types of things are not getting clean? Normally if the top wash arm is turning, you’re getting enough water pressure but it could be a little weak.
Try the mechanical cleaning test by smearing peanut butter inside at least four glasses and putting them in the upper rack if it’s not getting the peanut butter off then you have a mechanical problem with the machine probably I’m sure you’ve checked for water temperature proper detergents, etc. you should always use at least the normal cycle with a high temp wash option a dishwasher like this. The grinder in the pump could be broken and that causes very low water pressure in the top rack, but usually the top arm won’t turn if that’s really bad. Be sure the heating element is working as well. Let us know what you find. Happy New Year’s, John. | ||

Hello DADoES I crossed 60 in August so I understand!
Thank you Repairguy. John, Nothing in the top rack gets clean. I put in a plastic yogurt cup upside down. At the end of the cycle it looked the same as when it went in. Dry yogurt inside and not only was there no water inside, it was completely dry! I have used all of the cycles including Quick which has no dry phase. H2O tank is set to 120 degrees. (Candy thermometer at the faucet indicates 120). Cascade pod in the dispenser. Upon opening the door when the Quick cycle completed, lots of steam and heat so I'd say the heating element is working. BTW everything in the lower rack is CLEAN! Do any of you have a repair manual? Or can you guide me to one? It is time to dig in. Plus I'll call and find out if there is a parts warranty for 10 years. (Some Maytags had this). Thank you ALL! Michael | ||

I'm not sure which model you have but mine Maytag is from 2014 as well and it doesn't alternate wash arms. I think it's still point voyager at this point.. but I remember just after I bought mine, my model was discontinued

I checked the parts list. This model doesn't have an actuator to alternate wash arms. | ||

when my whirlpool 2005 point voyager died in 2014 (around 9 years old), while it was running, it started screeching this horrible sound...and I could smell burning plastic or something...I stopped it... drained it.. I always wondered if I had taken everything off and looked down in the area where the chopper is would have helped... but that sound was really bad... Like I couldn't imagine anything stuck in the chopper making that sound...

Point voyager dishwasher not cleaning in top rack
Hi Michael, I think you’ll find the solutions in post 12 or 13
It’s either clog going into the pump or the grinder itself may have failed if the 2 inch grinder disk is covered with food you need a new grinder. The other thing that wasn’t mentioned is the dishwasher might not be getting enough water try adding a half gallon or so of water when it’s running and see if the sound changes. One thing that threw me off initially as you said the top arm is turning. I don’t believe there’s any way that top arm is actually turning if it has enough water force to turn, it will wash dishes. If the dishwashers had a lot of use and you find the problem is in the pump it’s not ridiculous to replace the entire pump assembly. It’s about a $250 part. It can be repaired part by part. Also just depends on how much work you want to put into it versus how much money you want to spend , And if you find it’s not getting enough water just change the inlet valve don’t fool with trying to clean it.

Hello Michael! I have the same dishwasher from 2020, I believe your model was made just after they redesigned the pumps in these Maytags, I’m going to tell you how to get this taken care of. This model is essentially a manual cleaning filter and self cleaning at the same time, it has a food chopper to pulverize small bits but it also has a few plastic strainer filters directly under the lower wash arm to collect any heavy debri from getting into the chopper assembly. All you need to do is remove both racks, remove the back water feed tower and remove the lower arm and sump cover, once all that’s out you can easily pull out the two little strainers on the right hand side of the pump, and wash them out plus the metal stianless screen that sits over it to cover it all up. I will link a video for you, as you already mentioned I believe you seen some of these videos it’s very easy it only takes 10 or 15 minutes and it should solve the problem because the dishwasher cannot receive full water flow because it’s plugged. Now, if this doesn’t work, the only other problem is that the actual food chopper assembly is clogged as well and the best way I’ve seen to get to the chopper is by flipping the whole dishwasher on its top and taking the motor off directly to get into the chopper assembly. Let us know what happens!! These Maytags are awesome, absolutely love ours!
By the way, this model does not alter the wash arms it runs every arm at once the way it should be. I take mine apart once or twice a year to clean those out, upper arm always has good pressure. The reason the lower rack is cleaning and the top rack is in is because the lower arm always receives far much more pressure than the upper arm will so in other words if it’s clogged the lower arm is only able to pressurize to a certain extent and also check your back feed tube that runs up to the top rack arm and the roof jet and make sure there’s nothing in there clogging it. Keep us posted and I hope this helps!! Maytag kept this same motor and pump design until 2020 and they now alternate arms, no more good old fashioned wash systems based off the Point Voyagers anymore!

Hey Combo52, yes I am correct on this. I have the final generation of the same generation dishwasher that was in question from the author of this thread. He had the first year of the new Maytag dishwashers from 2015 when they redesigned their dishwashers switching over from the point voyager Jetclean series to the newly refreshed and revised models with the huge stainless steel arms that were sold from 2015-2020, they ended that wash system around 2020-2021 for the new wash system that alternates arms. Mine is a 2020 with the same older wash system as the author has in his model he is speaking of, I think you maybe thought that I had the brand new 2021 model. I will add pics of my model below, it was the final model of this 2015-2020ish generation and my model was made in late 2019 and purchased in 2020 model number MDB4949SHZ and I’ll add a photo of the model that comes up from the provided number by the author which does indeed have the same wash system as mine does that design was carried out for 5 years with a front fascia redesign in the middle of it where they refreshed the exterior design and my model is of the latest refresh they did for that series.
