Dishwasher has Gone on Strike!


Our LG dishwasher, a nice stainless model that is whisper quiet, decided to just not work when I had it all loaded up the other day. It has capacitive touch buttons on the control panel, and the entire assembly was dead. Did the usual and checked the breaker, pulled the schematic, and saw there was a power filter. There were multiple instructions on where "things" were located, so I pulled the dishwasher, disconnected the water and drain lines, flipped it on its side, and connected the power to check the three electronic boards.


  The power filter was on the lower back of the dishwasher.  All checked out good with this board.  I truly did not need to flip the dishwasher, just pull it enough to get to the back.


Next up was the actual "brains", and it checked out as powered up.  It's encapsulated in a gel, so no testing of any power output components without removing the gel.


No chance of testing the dishwater interface, low voltage signaling, and encapsulated like the mainboard. There were some complaints with this board failing on the repair forums, so I took a chance, albeit not much of one with Amazon Prime, and ordered a replacement.


The new part arrived via USPS from Lakeland (FL) in less than 36 hours, I replaced it quickly and the controls once again responded to touch control. I started up the record load of dishes just in time to avoid dishpan hands!  As a bonus, I'm considering applying for my LG service technician license as I've now been into the insides of my washer and dishwasher, with only the dryer left :)

    First off, I would have taken the dishes out before flipping...and secondly, I've never gotten anything from one of the Amazon facilities in Lakeland (4 warehouses plus an annex at the Lakeland airport that gets 10 planeloads a day) in that short a period of time!

    I did think about it, but the only items that actually shifted were some silverware as everything else just laid back in the racks. I get a lot of "stuff" I order from Amazon from Davenport, a few items from Lakeland. Lakeland goes through Tampa, Davenport straight to Venice (?) for Amazon delivery, Punta Gorda for USPS.

Sweat Equity

The little gym at the fitness center is tight, but has nice equipment.  They also have a "yoga" room, but their primary focus is outside on the tennis and pickle balls courts, along with a large community pool for aqua aerobics.  Nowadays I get my forehead temperature check when entering with a mask on, but can remove the mask when working out.  We also have sanitizer to clean the equipment after use, which truly needs to be a thing after the pandemic. I'm solo for about half the time I work out, so I pedal to the center on my trusty cruiser, all 1 mile of it. There's ample parking for my cruiser, on the rare occasion there is maybe half a dozen bikes if there is a tennis or pickleball event going on.  Most folks arrive on golf carts, followed by cars or on foot. It's a short walk to the center from the parking lot. The courts take up most of the property off to the east (right). For right now, I'll do a fast walk for a couple of miles and then cool down.  I&#

Avian Groupies

 A flock of White Ibis are working the shoreline along the edge of the 3rd hole (Heron course) behind our home, with a Common Gallinule staying a bit ahead and a Little Blue Heron in his usual spot, picking off anything the ibis are kicking up. The heron does work the shore by himself mostly, but if the ibis are out, he makes sure to shadow them.

The Coconut Telegraph Weather Station

 I had been wanting to install a weather station at our home in Tennessee for a few years but placed one here in sunny Florida.  I also wanted a station that could be seen while away, and there were a few options.  I chose an Ambient Weather WS-2000, which has an outdoor station and a small internal color screen that acts as a server for the distribution of data to a few weather services (Ambient Weather and Weather Underground).   Ambient Weather The outdoor station sits in the shadow of the house for northern winds, so it won't get all the gusting and such from some cold weather fronts, but other than that, it's been doing well!
