My pump started making noise, then eventually I started getting the "Pump blocked?" message. I drained the water and thoroughly checked for blockages. Even went as far as removing the pump and all hoses from the drum to the drain pipe -- everything was clear. I decided that, due to the excessive noise, I would just go ahead and replace the pump, even though it was pumping out water just fine.
I just finished putting in the new pump. MUCH quieter! But I'm still getting the "Pump blocked?" message. After studying the machine, I'm convinced it's a problem with the main pressure switch (See part #32 on the parts diagram)
It's as if it's not closing the switch (or opening the switch, whichever it's supposed to do) when the water drains, which tells the logic board that the water is drained and it's time to move to the next cycle.
Does anyone have any testing and/or calibration instructions for the main pressure switch?

clean the detergent tray especially the part for the conditioner. on some bosch the rinse water valve is seperate uie different valve for water for main wsash. check valve is not open circuit resistance should be about 3.8k. could also be due to low water pressure

I had a similar problem and found that the holes above the softner section were blocked by black mold. All I had to do was push a small wire into the holes to clear the blockage

Suggestions: First see that the exit hose behind your machine is inserted at a particular height, ie about 3 feet above ground level, then into the standpipe in your wall. If things dont work plug off the wall, open up behind, you will see a thin pipe coming down from the pressure switch to the drain area. Disconnect this pipe carefully from the top and blow into it, it should be free. If blocked clear, if broken or damaged change. Refit carefully.

SOURCE: message: drainage blocked
scgawlik,
Happy to assist you,
You said,
The pipe in the back is not clogged, it is wide open. When we removed
the cover for the pump in the front and open the valve, the water
obviously drains out. However, when you put it back together and try to
run it, it will go through a cycle and when it gets near the end of the
cycle that when the message appears drainage blocked and won't drain.
The electronic type washers , can be unplugged and after 5 minutes restarted and the system is then rebooted. This resets the system and clears the codes !
If the drain is not blocked then you have a faulty sensor or a bad pump

The 03 error code is the drain. Disconnect the drain hoses
and check for blockages. If no blockage "time" the drain interval. If
it's more than 6 minutes it's the pump. Also make sure you're using the correct
type of soap so the ball check valve on the bottom of the outer drum isn't
getting fouled with excessive suds. Also disconnect the drain hose from your
house plumbing and let it free flow on it's own. This will tell you if the
blockage is in your plumbing and not in the machine.
