Consumer Reports in USA published 5th of September 2014 the following on the Samsung dishwasher model DW80H9970US that recently was heavily promoted at the IFA trade fair.
The report, sent into us is worthy of note for people that may be thinking on buying one of these dishwashers.
“Talk about great expectations. Samsung says its new dishwasher with WaterWall technology “reinvents dishwashing.” But the filter on the Samsung Chef Collection DW80H9970US clogged in Consumer Reports (CR) dishwasher tests, and the dishwasher stopped working until we removed the 9 1/2 by 9 1/2 inch filter and cleaned it. Of the more than 100 models in CR’s current Ratings, this Samsung is the only one unable to handle our demanding soil load without consumer intervention. Because of this fact, we have judged this product a “Don’t Buy: Performance Problem.”
Instead of conventional spinning wash arms spraying water, the Samsung Waterfall dishwasher uses two bars that run the width of the tub. The rear one remains fixed with its jets aimed forward toward the second bar, which runs back and forth on tracks. Because the moving bar is angled upward, water bounces straight up to form a wall of water.
To test cleaning CR load 10 place settings of very dirty dishes that have been scraped but not rinsed. About 15 minutes after the Samsung’s wash cycle started an error code was displayed. This stopped the machine from completing the cycle. The machine then had to be opened, the filters removed and cleaned then the machine restarted. Once CR did this, the dishwasher completed the wash cycle.
Following CR standard practice, they called in an authorised repairperson soon after the dishwasher showed the problem. He was unable to identify the specific cause but told CR to call again if the problem reoccurred. It did. It happened in one of two additional test runs. CR then bought a second sample of this dishwasher and its filter also clogged, showed the same error code, and stopped working.
Samsung was made aware of the problem, possibly by the repairperson. In response to CR’s findings, Samsung told them that models manufactured from late September or early October onward will have a software update that continues the cycle even under heavy soil load. These changes will be made to future versions of the Samsung Chef Collection DW80H9970US we tested along with two similar models that offer the WaterWall feature, the DW80H9950US and DW80H9930US. The company has also updated the owners’ manuals for all three dishwashers to advise users to check and clean the filter should the error code display.
Samsung told CR in a statement, “this only seems to appear under Consumer Reports’ testing conditions and not in real world, everyday use.” But we don’t think you should have to stop what you’re doing to help your dishwasher clean your dishes. Nevertheless, the company says that if you have the same trouble, it will update the software of any of the above three dishwashers. “
