Does it fill with water?
Do wash arms rotate?
Place a glass upright in the top rack and run a wash cycle for 5 minutes.
Is the glass full of water?
I looked inside during operation and saw the following:
the upper arm is not rotating at all and water is not coming out.
the lower arm is not rotating either but the water is running out very well.
Before that we cleaned both arms and they don't have any blocks. All holes are cleaned. May be I put together wrong way or something like that.
