Bosch/neff/Siemens type DW E15 water in base

[neon_3SP_glow]

Had a run of these types (such as S51M53X2GB/N3) with water in the base activating float antiflood/ seeping into heat-pump element. Upon visit machine functions correctly with no visible leaks.

Water is often yucky yellow tint.

Where/how does the leak occur?

I check;

Door seals – if they get gunged near door hinges, water can sleep through and I directed through white plastic channel into center of base.

Spray arms – if they develop a split, water can force through seal same as above.

Empty/drain pump chamber and function/sink fitting.

Waste hose high enough so sink water can not back fill.

Torch in all areas of machine during cycle, looking for leaks.

If plastic to metal tub inspect seams for leak/signs of leak yellow crusts etc.

Are they slow leaking through the heat-pump?

If it’s drain pump or flow wheel related (overfilling) why is water not clear and why do they always function correctly when I visit?

Any help appreciated, thanks.

Not sure if it’s the same but have you asked whether a dishwasher cleaner was used recently. Have found that these machines trip antiflood after these have been used. Suds created by these enter base. Revert to liquid and raise float. Yellow colour can be cleaner colour. lemon fragrance.

The one place you haven’t checked is the Sump they tend to leak on the long eco setting place a piece of kitchen roll where the Sump seal sits and you should find its leaking there
