Our Bosch SHU43C dishwasher will not drain. We have looked

Resolved Question:

Our Bosch SHU43C dishwasher will not drain. We have looked in the large and small filters, stuck a small wire down the hole to try to clear it, but nothing. We also used Draino that is just setting in the bottom now (which I now know was not a good idea). I have taken the lower front panel off to see if the hose is kinked but I don't see much. Please help. Megan P

Repairman1981 :

If you remove the inner filter

Repairman1981 :

You will see a screw (t20) in the bottom holding the cover to the drain pump down

Repairman1981 :

Remove that screw and cover see if you can rotate the impeller by hand

Repairman1981 :

Also check for kinks or clogs on the sink end

Repairman1981 :

If there are not any then run the drain cycle and see if water is gurgling in the dishwasher. If it's gurgling there has to be a clog or kink in the line and you will need to uninstall it to see

Repairman1981 :

If it's not gargling then you have a bad pump

JACUSTOMER-a5y321o7- :

Because we have and inch or so of water in there I can't see numbers, is it on the left? right?

Repairman1981 :

numbers?

Repairman1981 :

its on the left

Repairman1981 :

it's a t20 size screw

Repairman1981 :

there won't be anything printed there

JACUSTOMER-a5y321o7- :

the screws. Also, how do we run the drain cycle?

Repairman1981 :

only scre down in there

Repairman1981 :

Press cancel drain or start a new cycle

Repairman1981 :

Cancel drain works if it's running, starting a new cycle works for about 30 seconds

JACUSTOMER-a5y321o7- :

We tried to run a cycle last night without dishes and nothing happened, didn't overflow either.

JACUSTOMER-a5y321o7- :

screws and cover removed, "impeller" rotating by hand. still clogged. No kinks on the sink end

Repairman1981 :

try and see if it runs with power

JACUSTOMER-a5y321o7- :

it runs with power

Repairman1981 :

then you have a kinked or clogged line you will need to pull the dishwasher to access behind the line

Repairman1981 :

If it's running and not kinked or clogged where you can see you will have to uninstall the dishwasher and blow the hose out fully

Repairman1981 :

you can remove it easily once the dishwasher and blow through the hose easily

JACUSTOMER-a5y321o7- :

Thats what all the websites indicated too. So we can just pull the dishwasher out, un-kink the hose and put the dishwasher back?

Repairman1981 :

yes if you have a flex water line, and long enough electrical, if not you have to disconnect these items

Repairman1981 :

Once you do then it just slides out

Repairman1981 :

did you need any other help on this one/
