Hello to my dishwasher got inside small screw and stop works, error i20 appear how can I remove it

Take the pump apart, look for a broken rubber flap

Try this

"Based off the information you have provided your Frigidaire dishwasher is showing you an "I20" error code. I have located that code and it is described as a drain problem that could be either your pump or control panel. I would recommend resetting you appliance, which can be done by flipping the household circuit breaker off for roughly ten minutes. If you continue to experience the error code I would seek assistance from a professional to come diagnose and repair your appliance"

Need a model number but the answer may be found in the trouble shooting section of you users manual which again is model number specific.

It is possible, but definitely before check if something is obstructed or blocked the drain pump. Error "i20" means there is a problem with draining water.

Hello,
I do not know the make or model of your Dishwasher but on most makes the screws on the inside edge of door are utilised.Normally the bottom edge and top edge,sometimes you can tell by the type of screw head or rust.Some model may have a small plastic plug in the side edge of door and if removed you will gain access to the screws.

Hope this helps.

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.)

try washing the dish washer out with a good drain unblocker the system gets cloated up with grease, then use a dishwasher salt with the washes this will help to remove the suds ets, most dishwashes have a compartment to put either liquid or solid dishwash aid in try a different aid, also if you use tablet form i desolve it first in hot water in a small container
then place that into the dishwaser on the lower shelf, that helps

if that fails then try emptying the over flow try found behind the kick panel below the door. 2 phillips screws will be found either side under plastic screw covers, behind kick panel you will find the cover for all internals remove a total of 6 screws from these covers, then with a torch you will see the internal workings of the machine. located at the bottom of it all is a small kidney shaped tray that may have some/alot of water. this is the over flow tray. empty by soaking up the liquid with a sponge. reassemble then try starting it.

I just had the same issue as a result of "mother-in-law" using regular liquid dish detergent in both drawers. After numberous attempts of cleaning out each drawer it still was beeping and attempting to drain both drawers even when the water was drained it continue to run and beep.
My presumption of what occurred is the wrong soup caused so much suds that it triggered the flood sensor. I removed both drawers and discovered water in the base area and moisture throughout. After disconnecting the power to the unit I removed the white plastic cover and exposed the small circuit board. I disconnected the power leads and the screw holding the board in place and lifted it up a bit. I then used a hair dryer for about 15 minutes until the entire area was dry and put it back together and has worked just fine. You will see a service diagram taped to the back pannel when you remove the bottom drawer. It has additional information on various error codes and the instructions on how to trouble shoot problems. I would also remind you to run water in the units if the cause was due to the wrong type of soap as the residue will continue to recreate the same problem.

I hope this helps.

Got a possible solution from a brilliant guy named Jake on another website and thought I would post it back here.

"Check the door vent on the inner side of the door, that should just snap out, I have seen those clog and start making more pressure inside to make it leak from the bottom. Jake"

I checked mine and got a nasty surprise. Who knew it could get so dirty.
