I have a Matag Model# MDB4100AWB dishwasher. I removed the spray arm to clean out clogged jets. Upon reassembly I can not get the thread started on the spray arm keeper cap. Is there a trick? Please help. Thanks Jason

Re: Matag dishwasher reassemby prolem
Try turning it the other way.
Some of these things have left hand threads (as in "you have to do it up to get it off") so they won't unscrew themselves in use - and this is often made more confusing by the fact that you're trying to screw something on towards you.

I have an older dishwasher also and recently mywife also complained about it not cleaning right... so me being the man I amtried in vain to clean the things... Bought new spray arms online and installedthem in minutes...now the thing works like new... However I have also foundthat if the heating element goes bad then that also can mess things up bad...So I would buy new spray arms, and also check out the heating element to makesure it is working... Here is a tip that will help you with the onlinebuying...
Dishwasher SprayArms not Spinning
The spray arms could possible be clogged or blocked with debris that wasn't chopped and removed by the filtration system. You can easily remove the spray arms (upper and lower if your model has both) and flush them under the faucet. I have sometimes had to use tweezers to remove bits of paper, plastic or even bone from the jets. This would improve the water flow and give the jets the strength to really "squirt" your dishes!
My first guess is to check the spray arms are not blocked from spinning by a large plate or utensil and /or the spray arm orfices are clogged. Removal of the spray arm should be fairly simple and run water through the center of the arm and see if it comes out the jets.
The spray arms can usually be removed by unscrewing (clockwise or counter clockwise depending on brand and model), or squeezing a retainer to release the arm. Before removing the spray arm, place the spray arms (all) in a specific position and activate the dishwasher for a few seconds with wash action. Then examine the position of the spray arms to determine if there was movement from the spray arms. If not, then the spray arm(s) are probably clogged and restricting water flow (which makes them turn). Make certain that you are positioning the plates, glasses, etc. in the dishwasher so that they have access to the water. If still no luck, contact an appliance service company.
could be the plastic shaft extension that screws onto the motor shaft to drive the pump. The threads on the plastic extension would sometimes get stripped out so that even though the motor is running, it isn't driving the pump mechanism. Assuming the dishwasher is filling with water and motor is running during the wash cycle. also check spray arm openings to make sure they aren't plugged up.
Not familiar with this specific model, but I had a similar problem where the water jet slots in the dishwasher's top spray arm were blocked by food debris. The filters were nylon and had started to disintegrate, and when water was recirculated debris was pumped round & blocked the jets. Suggest check your filters are ok/seating properly & then check the jets are not clogged. My spray arm came off easily to enable me to clean it out.
metal sleeves at the end of the lower spray arm?? dont remove them they only protect from hitting against heate and melting. should be a center thumbscrew in spray arm loosen that nut and should come right out, pokin with wire or toothpik willwill clear joles but you gotta remoe the debris from the arm other wise first run will shoot right back nto holes
