The Saga Continues:....
Last time I went out to the house, the customer complained that since my initial repair the fridge was making a loud noise when the water valve was engaged. As previously stated, I attributed it to water filter freezing since the customer had the fridge set to 34 degrees. I increased the temp, but I did not hear any rattling sound.
The other day got a call from the customer again complaining of excessive noise whenever water was dispensed or icemaker filled with water. Damn, this beastie keeps returning like some Hi tech Jason minus the goalie mask. Okay... maybe I didn't secure the water lines in the back of the fridge but as soon as I pressed the dispenser, I quickly took cover as it sounded like the beastie got a hold of a Halo pulse rifle and sent several plasma burst my way. The hammering sound was incredible. I know it did not sound like this when I finished the repair a few weeks back. I thought maybe air was entering the system so I removed and re-tightened all connections but the beastie continued to fire at me.
Never to shy away from a fight, I figured I had to reengage and access the filter assembly to check the john guest fittings. Now If you have not had the pleasure of changing a filter housing on this type Samsung, call yourself blessed. There are 4 water lines running into the cassette where the housing is located....you have to remove the lines from their connections to the house and water valves, including the many restraining clamps. Not so bad you think? Not until you realize that line to the dispenser ran through the top of the machine near the left hinge. You have to remove a plate that runs across the entire top of the fridge. But before you can do that, you have to take off the hinge coverings on both hinges to get access to the screws. Once you have access you have to remove the line from the JG connection on top of the fridge and pull it through the fridge. Then you gotta remove all the food in the ff section..just to get at the cassette, remove the filter then the screws and disconnect the cassette's light connector, pull the cassette out...then remove screws from the cassette then pry the cassette open and voila...the filter housing and a small reservoir tank. Then reassembly.
THE SECRET REVEALED
Now I wasn't looking forward to doing this again. I'd rather try and drop a bomb down the anus of a fully operational Deathstar. But with my battle plan in hand, "once more into the breach" I shouted. However, just before my charge (one that would certainly have made Alfred Lord Tennyson proud), the customer said "I noticed that it doesn't make that sound when I run the water in the sink at the same time.
@$#^@! high water pressure! That was the beastie's secret weapon. I didn't check it before as this was not why I was called out in the first place. The noise was a new phenomena and the only added element was replacing the filter housing. Anyway, I removed the line to the fridge, place it in a bucket and turned the water on. That line shot out of that bucket like a bottle rocket. I hadn't seen so much water pressure since I last washed my truck at "Powershine." Then I remembered. The first time I accessed the water valve, I asked the customer if he had already turned the water off...he said "no." I asked him that question since it looked as if the valve was already closed...it wasn't. I was just turned waaaayyyyy down.
The Previous owner or fridge installer must have minimized the valve to reduce pressure. Unaware of this, I had maxed it open during my initial repair. It takes about 10 minutes for the pressure to build to its insane level so I did not hear the problem during testing of my initial repair. I turned the valve almost off and the water still gushed out of the dispenser..but no more pulse rifle...not even after ten minutes. I advised the customer to have water pressure checked and possibly reduced to prevent causing other appliance problems. Two freakin extra visits for nothing....i swear as I walked out the door I could hear the beastie snickering.
