I have two questions. Is my DW installed correctly? Has it been damaged from being used while improperly installed? Here are the details....
My DW does not drain through a sink. It's drain hose connects to plumbing in the basement. According to the DW installation manual, an air gap is required for this type of set up. I found this on page 1 of the Frigidaire DW (model FGHD2433K) manual. See section 4.3, under figure 6 - http://manuals.frigidaire.com/prodinfo_pdf/Kinston/154427301.pdf
My DW was installed in July 2010. It ran great for 3 months - very quiet and super clean dishes. Unfortunately, it has been downhill since then. It slowly started sounding like a jackhammer during the latter 2/3 of a run. Frigidaire recommended a local appliance repair company and a technician came out on 1/4/2011. He determined that it was installed improperly - no air gap.
The installation has since been fixed... I think. The original installer (a local reputable plumbing company - not handyman or DIY) come back out on 1/ 14/2011.
This was the original set up we used for 6 months: DW drain hose ran through floor and connected directly to a pipe in the basement that connected directly to our main sewer line in the basement. No P trap and no air gap. Drain hose is looped on side of DW as required.
Here is the new set up: DW drain hose runs through the floor and connects to the same pipe as our washing machine in the basement. This pipe runs approx 6 feet up a wall. Washing machine connects at the bottom and DW at the top. The top of the pipe connects to a P trap and then to our main sewer line in the basement. Does this sound OK?
Now, after the new installation, the DW is slightly quieter, but still loud AND doesn't clean; leaving small particles and film over all the dishes and glasses.
Also, if you need more description of the drain plumbing, I can provide it. A tech is coming back to look at the noise/cleaning issue again. All I know is that the non airgap installation might have caused siphoning of the wash/rinse water. Can siphoning cause damage to a DW? Should the original installer replace the DW?
