My LG Technical Manual shows a maximum of 96" from finished floor to top of the drain discharge for a combo unit.
My open Y drain connector is only 32 inches in overall height.
It is still however my opinion that more than likely the small amount of water that should be normally passed back into the tub through the anti-siphon hose with the correct orifice restrictor was factored into the original design and engineering of this combo unit. In other words the anti-siphon and cooling water mist solenoid orifice sizes were both determined in the final construction and manufacturing process in conjunction with the heating element output and total blower output coupled with the thermistors, dry tube and bellows condensate system and the amount of clothes placed in the unit so as to give optimum dry times and results.
I also feel that this small amount of water returned to the tub through the anti-siphon hose is probably the main reason why the clothes are still slightly damp instead of completely dry after a dry cycle. I have never had completely dry clothes in the six years I have owned this machine until I disconnected the anti-siphon hose from the tub!!!!!!!!
Anything that adversely affects any of these very critical different components that must all function precisely together as designed and engineered will dramatically decrease the ability for this combo unit to dry clothes efficiently and in a timely fashion.
I WOULD ALWAYS BE HIGHLY SUSPICIOUS THAT THERE IS TOO MUCH WATER IN THE TUB FOR SOME REASON IF YOU HAVE A DRY PROBLEM WITH A COMBO UNIT...
I have noted that my clothes dry better now than they ever have with the anti-siphon hose plugged and completely disconnected from the tub. I am not advocating that anyone else do this, but it worked for me.
I am totally happy with my service>>> SMILE>>>and the price was right...(I actually saved over $900.00 from the cheapest estimate with many more new parts than they quoted...to include a new door seal....Here's to all the "do it yourself repair people!" If there is a well, there is always a way!!!!!Keep coming back to this site, it works!!!!!!!!!!!!!!
