I noticed something on a LG dryer the other day. It was stacked, so I ordered parts and scheduled it with a helper. We took it down and tore it apart to install new rollers, belt, and pulley, The left side roller on the front bulkhead was totally destroyed. I replaced it with the shaft/pulley assembly and just the rollers on the other 3, cleaned and lubed of course. We put it together and tested it. It had a pretty solid drum seam thump when running.
We took it back apart and I found the drum did not touch the right front roller at all, maybe 3/8" or more gap. When I checked the panel I noticed there are 2 holes in the area of that rollers shaft location. The dryer was kinda toasted inside so there was a clear mark where the shaft was mounted, so we are certain the new shaft was in the same location the factory had used. I move the shaft to the other hole and the dryer ran smooth and quiet.
I wonder how often the factory uses the wrong hole, and this might be causing the cracked drums. In the wrong position, that roller does nothing, and the left hand roller bears all the weight in the front. The excess load on a single point working on that seam could be causing the cracking, at least in some cases.
How many times have you run a call that the problem was the Food-Safe hoses not allowing waterflow into the washer? Well, today I had another one and for added drama toss in a customer who thinks he knows what's going on, but actually he is just an ass.
The complaint was no water entering machine, no hot or cold fill. I get there, turn it on, and I can hear the coils on the fill valve humming. I check to see if the water is turned on and discover that these are Flood-Safe hoses. I remove the hoses from the washer ends and show the customer the hoses are not allowing any water to pass.
Now assman decides to inform me that "the check valves have been taken out" and the problem "must be the washing machine". I tell him the check valve is inside the hose, and it most certainly was not removed, although I could see someone had broke out the centers of the flow restricters. So, I get a normal hose from my truck and put it on the cold valve, now water goes in. He doesn't believe me, so I do the same with the hot. I did the demonstration for him a second time and this dipshit still says the problem can't be the hoses because his insurance company said he had to use them. I tell him those hoses will not work and I find them bad all the time. At this point I decide my visit to Moronville was over, I'll leave him with his special hoses and what ever mental defect he caries.
Before I left, I told him if his insurance company said he had to use Flood-Safe hoses, and he had a flood claim, they would demand to inspect the hoses before making any payment. If they found the hoses modified, you can be sure they will not pay for any damages.
