Can anyone please tell me how a Blomberg 1503 regulates it’s fill level? Ours is not filling full enough. Is there a sensor or is it based on a timer?
Regards
Re: Blomberg 1503 fill level regulation?
Why do you wish to know?
Modern washing machines are set to use sufficient water, based upon the absorbency of the load: cotton towels will demand more water than polyester-cotton items. Machines no longer fill right up the door.
It is not a good idea to fiddle with the hydraulic system as problems can result.
If you are getting too much detergent residue/soap suds, try reducing the amount of detergent used.; and / or activate any higher water level rinse switch.
The cotton cycles usually have a more efficient rinse and spin profile, whereas the delicate cycles omit the intermediate spins, but have higher water levels.

Basic water level control is by displacement of air from a collection chamber, up a skinny tube to a diaphragm switch. Modern machines with digital control may use the length of time to reach this level as a marker for timed fill – wool programmes are usually much deeper, for instance. Simpler systems use a multi-level switch.
The Blombergs have a known issue with the collecting bell on the back of the drum, it becomes choked and causes false levels.
Power off if you need to inspect it.

The machine fills enough to wash but not if it’s a large load – a bed spread for example. It used to be fine and suspect it is now a problem is because the *insert expletive* plumber put the WM feed in the new bathroom on the gravity supply even though I asked him to put it on the mains. As we have a bungalow the pressure is only about 0.5 Bar and I noticed yesterday the WM instructions state that the pressure should be between 1 and 10 bar. Hence why I am asking if anyone knew the method used to determine fill level. With the 1000 different essential DIY jobs I have lined up I don’t want to have to run a new feed if it won’t make any difference or if the problem is something else.
I note the pressure switch appears to have a three position sensor, well it clicks three times if you blow in it.

Washing machine fill valves have a ‘pressure reducing washer’ built into the valve, behind the plastic filter.
On Ye Olde Hoover machines, this was removable, to allow for installations where gravity-feed cold water was used. (The hot water valves on the old Hoovers had no such washer, as they were expected to be fed by gravity; however, should that valve be connected to the cold mains, a washer was available from Hoover).
