Question about Bosch Nexxt Premium WFMC6400UC Front Load Washer
we set up our drainage in our washer through a 3/4 hose that drains directly to our main abs drain out to the septic system. the hose rises to about 7 feet above the floor, then 10 feet over to a wall and then down 1 foot to the abs drain. every thing was going fine for a year or so until we got some error 4 codes.
I've checked the septic line (drains fine), and cleaned out the 3/4 hose and the grey drainage hose that attaches to it...they were pretty blocked by soap.but got them cleaned out.....we are still getting the error 4 code though my wife claims it only happens on the 2+ load of the day.
we are wayyy out in the middle of nowhere, and getting a bosch repairman out here is expensive...any help, including up to replacing of computers/sensors would be appriciated.
After browing a little more on this forum, I found the solution to my problem.
There was an hairpin stock in the rotating device that is located behind the front plastic cover.
Thank this website was very useful to me. Hope it can help someone else too!

The problem here is that the waste pipe is rising to high up above the floor,, the top limit should be machine height ideally. The pressure built up by the water is not manageble by the drain pump.. in reality the waste water is acting as a blockage hope this helps
any questions dont hesitate to ask im here to help cheers got to go

Tips for a great answer:
You need to check the drain pump externally to see if the pumping is good Also remove the drain hose clamps and remove the drain hose flushing to clear off all dirt. Now test using power to see if this works and can be simulated. When refitting, the hose must be tightened properly. If the pump/valve does not work even with power then it must be replaced. If there is intermittent power to the drain valve/pump then the program controller unit is a suspect.

Finally the washer must be placed with a tilt- use a spirit level- so that all water will drain to the outlet port and thereby there is no residual water remaining.
