Siemens SE26T251GB – water intake problem

Re: Siemens SE26T251GB – water intake problem

Thanks, Martin – you just saved me spending money on cleaner stuff. I’ll just do an occasional hot wash with powder detergent but no dishes.

I could always feed the machine with hot water, and in reality being heated by gas it might even work out cheaper even if it uses more.

That is precisely what I was eluding to. The only way of preventing any gunge build-up in the water inlet side is by connecting it up to a hot supply. Fortunately in your case, your machine is more than capable of accepting a hot water feed. The only important issues to consider however is two-fold. 1) There must be sufficient head of water (1 bar or above). 2) the incoming water must NEVER exceed 60 degrees C.

I must clarify that that option only applies to certain models of dishwasher. In your case it will be fine, it will work just fine and be more efficient and effective to boot!

💡 Ah, I’d just sussed that from your comments and then reading the book. That says you can do it but they “don’t recommend it” 😕

Will have to mull over the pro’s and con’s. Would have to do a bit of re-plumbing, and when I refitted the kitchen (same time as I bought this) I made it SO neat behind all the cabinets which will have to come out. So all that work versus perhaps routinely cleaning this out every 18 months or so. Also, quite a long dead leg between the boiler and here so hot water may never make it ! As this machine does take in water in several small sips when it is working properly, it would also put more wear and tear on the combi boiler.
I reckon I’ll leave it. I think this is a fairly economical machine as far as electricity is concerned, so savings would be there, but not huge. However, good to have been told all the answers, and I’m sure they will have been helpful to anyone else with a similar problem. Thanks to all once again.

I have an identical (or very similar) problem, also with a Siemens machine 5 years old. We use it on low temp washes mostly, which I guess has not helped. It “chugs” 10 times or so when filling at 2 or 3 second intervals. Model is SE26T550GB.

from reading the thread, I understand that a pipe or filter is partly blocked under the machine, and has become so due to a combination of the cold water fill and the initial “cold” rinse of dirty plates (BTW, we rinse our plates pretty thoroughly).

Question: does the hot water go through this are during the wash cycle? if so, can I put some washing soda into the machine when it fills for the main hot wash, and would this help to clear the blockage? Or would washing soda cause damage? if not, how much should I use?

No!

Certainly not!

Martin: thanks for your reply.
So would I be right in thinking that
1 it needs to be cleaned out manually?
2 access is by tipping the machine backwards and going in from the base? or do I need to remove a panel below the door?

Thanks for your help.

My pleasure and if you read this thread from the beginning your 2 questions are already answered. 😉

Re: Siemens SE26T251GB – water intake problem

Hi, downfield – just to give you a bit of encouragement it turned out to be quite easy to do. Not sure how similar your machine is on the outside, but I assume they’re almost all identical inside. On mine, needed to take off the top (2 clips at the back and it slides off. A couple of screws in the front edge of the machine each side releases the sides, removing a self-tapping screw on each side of the base part then lets you lift that away. There is a metal plate behind that you need to unscrew and put to one side (there are wires attached, but enough slack to get it out of the way). In mine then there was sound deadening stuff, and then – finally ! you can oik the pipe out and clean it. I reckon mine was blocked with congealed fat/grease rather than chunks of food waste. Don’t see how you can avoid that happening even with rinsing the stuff – there will always be grease to be washed off. I’m reconciled to it being a poor design issue in a relatively expensive machine, and having to clean it from time to time.
