Maytag Washer "No Hot Water" Connundrum

\\"Share your knowledge. It\\'s a way to achieve immortality\\" --Dalai Lama -------------------------------------
I have a Maytag washing machine, Serial No. LAT7304AAE, that does not dispense hot water. I have tried the usual and more obvious suggestions, but the problem persists. Here's what I have done:
1. Verified that hot and cold water is available. 2, Intake hoses are connected to water valves that are turned on. 3. Checked the screen on the water inlet valve. There are no obstructions. 4. Replaced the water inlet valve with part #22001274. Replacement of the water inlet (solenoid) valve resulted in no change.
The washing machine will not dispense any water when the hot water setting is selected. Resetting the temperature control knob to cold water results in cold water. Warm water setting results in dispensing of cold water only.
Please note that the symptoms before and after replacing the water inlet are identical. I find it hard to believe that I have a brand new part with the same problem as the original part.
Any suggestions? Unfortunately, I do not have the model number of the machine handy. It is located in another house and I don't have immediate access. Can the serial number be cross-referenced to determine the model number? This is an older top loading machine. The control panel consists of push/pull type knobs.
Thanks for your suggestions to help me solve this problem.

Sounds like whatever sends the signal to the valve isn't sending the signal. Probably a circuit board somewhere. Shoulda checked with a meter before replacing the valve.

you could try reversing the wires for the hot and cold valves and see what happens, that will tell you which way to look for the problem

Baylynx had written this in response to http://www.thestuccocompany.com/maintenance/Re-Maytag-Washer-No-Hot-Water-Connundrum-347166-.htm : I thought about doing just that. I suppose it can't hurt anything. If I reverse the wires and start getting only hot water and no cold, I will at least know that there's a bad connection somewhere in the wiring harness that controls the hot water valve. Does this seem reasonable?
Also, If I use a meter to check the resistance and voltage at the solenoid, what should I be looking for?

Just verify that they are the same for both solenoids.

Baylynx had written this in response to http://www.thestuccocompany.com/maintenance/Re-Maytag-Washer-No-Hot-Water-Connundrum-347348-.htm : Okay, here's what I found:
Hot water solenoid Voltage = 0 Cold water solenoid Voltage = 120
After reversing the wires:
Hot water wolenoid Voltage = 120 Cold water solenoid Voltage = 0
Ran the machine with wires reversed and got hot water only on the cold water setting. No water is dispensed on the hot water setting.
So, is this a wiring problem or a control panel problem? Seems to me that the hot water indicator is not sending a signal to the solenoid that dispenses hot water.
Is this fixable? This is not a newer digital control panel. It's the old style knobs that are manually rotated to select a setting.

Of course it's fixable, anything is fixable, it's just a matter of locating and replacing the defective part. Does the washer have a schematic? Most do, look inside the control panel for an envelope. Trace out the circuit, I would first suspect the switch that sets the water temperature, but there may be other things in the circuit that could cause this.

Does this washer use an electronic control board or a mechanical timer? If it's electronic, there's usually a triac on the board that controls loads such as the water valves. If it has a mechanical timer, then one of the contacts in the timer, or the switch for selecting the water temperature is probably defective. The serial number is not really useful, what we need is the model number.

Machine has a mechanical timer. You rotate to select the type of load and pull the knob to activate the cycle. Water temperature settings are selected by rotating another knob for hot, warm or cold water. Please see my latest findings in previous post. Thanks.

So you isloated that the solinoids are NOT the problem. Problem could be the wires or the switches.
So now you swap the wires at the temp control switch to isolate the problem to the switch or the wires. It is probably the switch.
You could just wire both together and use the thing with WARM water all the time.
