Hi everyone,
I’m trying to repair an older Daewon DIB-1500R PowerWash bidet seat, which was sold in Germany under the VEBRA DIB-1500R PowerWash brand.
The unit is actually still working very well: the nozzle extends, the water heats up, the dryer works and water reaches the wash nozzle. However, during the wash cycle, water is flowing backwards into the small air tube of the Bubble Wash / air-mixing system. It then runs out through the air intake opening next to the nozzle.
I have disassembled and descaled the nozzle and the water path. I also removed the small transparent T-shaped air-mixing/Venturi part with its thin air tube (see photos) and descaled it. The passages are open.
When I test this part separately by injecting water through the normal water inlet in the same direction as in the bidet, water also comes out of the small air tube instead of the air tube producing suction.
Does anyone know this DIB-1500R Bubble Wash system?
Is water coming out of the air tube a sign that this Venturi/air-mixing part has failed, or can this happen during a simple syringe test even when the part is working correctly?
I would also be very grateful if anyone knows the part number or a source for a replacement air-mixing/Venturi part for the DIB-1500R.
The bidet is otherwise in very good condition, so I would much rather repair it than replace the complete unit.
Thanks very much for any help!
