Bosch SMV69T10GB/11 E25 error

[bisebreath]

My dishwasher ends with an E25 error displayed. Turning off then back on again will drain the dishwasher? No debris in the pump drain area and the impellor spins freely. Any ideas? It appears to wash the plates perfectly just finished with that error message?

could be a blockage , a worn drain pump or a board fault

So is that a “get the professionals in” job? I’m not sure how these things work but I assume it rinses, drains, hot washes, drains and then dries? If that is the sequence it drains first but fails to on the final drain and the error occurs after about 2 hours of a 2:20 wash. Thanks Pete

Hi Dave, the pump works fine and appears to have no blockage as the first thing I do in the morning is turn it off, back on again, start a new cycle until it drains then reset it then turn it off ready for the next wash later that day. Everything is clean. Just water in the bottom at the end and an E25 error message. Any advice would be grateful….

is the drain hose standard length or extended ?

Hi Pete,

Did you ever find the issue causing this, I have the same problem with the same model. I’ve stripped it down a bit and made sure all hoses are clean, taken out the heat exchanger and cleaned it the best I can, but it still errors at the end of the cycle.

It doesn’t appear to be the drain pump, as it drains a number of times during the cycle, its just at the end. And as you’ve said, if you start it briefly again it will drain the water.

Was wondering if there’s some sort of sensor that might be glitching.

[electrofix]

on these models the pumps are the sensors

how old is yours ?

I think it’s about 15 years old. I have done some maintenance on it over the years to keep it going, but it’s been working fine for a good while now. I guess it’s at that age when parts may start failing though.

ok
let me have Enr and Fd no so i can see which system it is

Dave

[GlassyMan]

Enr – smv69t10gb/16
fd 9001

[electrofix]

ok its the later system

from info it was built jan 2010

the drain pump acts as a empty detector

fault codes comes up as

Drain pump unable to rotate,
attempts to clear failed.
 Check for debris at drain
pump

drain pump is part no 611332

youi can get on Amazon for about £20

now i cant promise a cure but its not expensive if it fails

you could try removing the pump and check for debris first

Thanks for this Dave.

So you think that even though the drain pump operates ok at multiple times during the cycle, there’s possibly something in it that’s maybe causing the error just at the end. Maybe a sensor or some slightly different operation that it may only do at the end.

I’ll have a look at stripping it down this weekend to get to the pump. Let me know if you’re aware of some good instructions/video, I’ll have a search around. I presume it needs to removed from the bottom somehow.

there is no other sensor. they used to use pressure sensor but not now

they measure the current of the motor to determine if its empty or not as when the motor is under load it draws more current

that means its either a motor fault or a board fault

as the motors age the bearings fail. as the bearings fail the motor draws more current as the rotor contacts the casing. This fools the board into thinking that its not empty hence the fault code. it can also be caused by debris jamming the pump rotor

and yes it seems odd it should only fault out at the end

the question you have to anser now is do you want ot gamble £20 to see if you can repair it
