Maytag mvwp575gw ATC. Not sure if this is a victory or not?

Checkrate/Likes I posted this separate, so I did not hijack the new GE washer thread. I played around with that stupid ATC sensor again on the Maytag which seems to dumbs down the water temperature for the Normal "Eco" load only. I have my water heater set at approximately 120 degrees. When set to hot, I have not noticed it switching to cold for the deep water cycles. Anyway, I unplug my washer between uses. Good or bad, I don't know. But I unplug it. I mention this because it could make a difference as I think this might "reset it each time?". I do use a hh surge protector as well. With the sensor relocated, I can almost always get a tap hot half load for the FIRST Normal "eco" load only after it is unplugged for a the day and only for that first load. My house is 80 degrees too. Yes, I try to cut costs where I can, but I need hot water for some loads! After that, it becomes a frustrating game trying to get tap hot for the next Normal load. So was it because the area where the sensor was at gets warmer after a load is run even though it was sensing air now? I tried relocating the thermistor so it was no longer enclosed in the console panel. I got mixed results still with subsequent loads. Tried unplugging for ten minutes. Nope, that does not appear to be it. So what changes between the first load that is run after the washer has not been used a day and subsequent loads that cause the trick to no longer work? Perhaps, I am at that fine line where it decides to activate hot or not. In the winter, relocating the thermistor to sense air temp works because the air temp is 60 maybe 65 at best. So, I placed something cold to the side of the sensor. This is NOT smart. It can shock the stuffings out of you. This was suggested by someone here on one of my posts. But, hey, it does work. Half tub of tap hot. And I can switch back and forth between tap cold and tap hot as needed but it has to sense the water temp as really cold. The problem with the ATC sensor is if if thought my ground water was warm enough, I get a barely warm wash. If it senses colder water, I get a half tub of tap hot! That is a huge variation between barely warm and tap hot! It was really a poor decision on Maytag's part to make this the only smaller load option. I am so frustrated. Maytag fell short. GE and LG can't get it right either, and these products were meant to compete with this washer. Hello. Forget the ATC sensor, add a water level switch, make a better quality build machine, make a basic model with mechanical controls, offer one with more electronics for those who want that, etc. At least with my portable one, I can just turn the cold off and it will fill with the amount of hot needed. Some airhead ruined it too by allowing it to fill only half way for a large load. I have to add a 2 gallon bucket of water. It is a 1.6 cu. ft. It might be under the amount covered by those eco restrictions. If not, make it a tad smaller capacity so those stupid restrictions do not apply. I should not have to do this! These sensors and restrictions are garbage and yield inconsistent water temperatures. I got a lot more than a 15 degree variable. Ok. I'm done venting for now.

Checkrate/Likes *Edited...* I appreciate the tip to try something cold next to that thermistor as it helps troubleshoot the issue. Is it a temperature sensing issue or programming issue? Looks like it is a temperature sensing issue. Anyway, I just meant don't try it. That part if touched can shock the stuffings out of you. Plus, leaving it exposed is not smart. If something fell on it, it could have negative consequences.

Checkrate/Likes on the Cabrios....I found it best to remove the restrictor on the HOT side.... leave the sensor in place.... and have the water heater set at least to 140...mine is set at 160.... models may vary with programming, but even with mine dubbing down the hot side 10 degrees, it was still a hot wash.....even WARM was at a good setting... factor in too, your most likely starting with a cool washer, and the clothes are probably cool/room temp...your taking a temp drop there as well....and your only talking a few gallons on HE machines, versus traditional TLers using upwards of 21 gallons.... YMMV

Checkrate/Likes *This was IT.* I do a lot of smaller loads now but still need to be able to do larger loads. My current setup was just not practical now. I am not a fan of using the washing machine outlet faucets to control temp as this increases wear/tear on something that can get expensive to replace. This washer has an automatic temperature sensor and fills by alternating hot and cold. There are no restrictors that limit flow of hot or cold to the inlet valve. Whatever temp the thermistor senses determines the programming. So it appears that locating the sensor outside the cabinet and carefully placing one of those plastic ice packs/freezer blocks one can use in lunch boxes very carefully to the side withOUT touching the thermistor does the trick. Every time :-). With that said, don't try this at home. It is ridiculous that people have to risk electrocution to get tap hot because they don't want to run a full tub of water. Maytag needs to add a water level control. It can be as simple as adding a deep fill switch that allows to water level choices at least for Delicates, Mixed, and Powerwash. Really, after two years, that is my only real concern with this washer. Leave the Normal "eco" as the cycle put there for government testing. With that said, it does work well for quick washes and normal loads that don't need tap hot. Issue resolved.

Checkrate/Likes 1 This is one of the concerns I have with these commercial Maytags when I looked into them. Personally, I like using hot water for some loads and I'd rather have a machine where I could get hot water straight from the water heater tank without having to mess with anything. That's just me.
