Dear Customer,
As per conversation - during our visit all indicators were showing that you have a drain pipe blockage.
As we removed drain hose from the drain pipe and drained water well into a bucket in front of you showing that appliance draining water properly. Completed 2 drain cycles.
Your wife confirmed to technician that sometimes water going badly in the kitchen sink.
Technician tried to poke the drain pipe with a screwdriver and something obstructed it.
As per conclusion was made that drain pipe is clogged as when dishwasher drain was connected back to drain it did not work properly (however drained well when disconnected and drained into a bucket 2 times in a raw).
Magically plumber confirmed the opposite. Anything is possible.
We offered a free of charge service and repair for you; to make sure that we double check if mistake is done by us and complete the repair free of charge so you don't encounter any further charges from other companies - you rejected.
We respect your decision and we would be glad to see you back, depending on what the other company tells you.
Regards
Igor
