Are you sure that was the error?
I do not see that one in the tech manual.
I do see an OB. Could that be what you saw?
There is also an OE code. This seems closer to your 03 code. The OE code is a drain error. It is saying that the unit took longer that usual to drain OR did not drain fully. This can usually be remedied by cleaning the pump out via the cleanout located on the front panel in the lower left hand corner. Have a pan ready for any excess water because it will drain out when you remove the cleanout basket. If there is nothing in the basket then you may have a pump that has failed OR is failing.
Let me know. I will be on most of the night.
Thanks. You are right. It is OE. I will take a look.
I will be here.
It worked but I underestimated the amount of water that came out. It was quite a mess! The basket was filled with gunk. I guess I should empty it out once in a while? There is also a rubber tube there. What is that for?
