Maytag: Gen2 Serial

Maytag Gen2 machines are those with "PR" or "PD" in the model number, such as MDE22PRBZW or MFR80PD. The known exceptions are MLG3xPD and MLG4xPD stack dryers, which use Gen1 (non serial) controls. Primus washers also use Gen2 serial controls.

Required parts

Reader
Cable harness (02-06-38 or 02-06-48)

Cable 02-06-38

Cable 02-06-48

WARNING: The cable harness uses a similar 6-pin connector on both sides.

Ensure to connect the side that says "Reader" to the reader.

This will be the translucent connector. Connect the solid-colored connector the machine. This is shown below.

Do NOT mix up the sides as this can damage the machine!

Installation Steps

Step 1: Turn Machine Power Off

Step 2: Remove coin-drop (for Card Only Installs)

Step 3: Number the reader using the DIP Switches

Review our: Reader DIP Switch settings article for details on how to set the Card Reader's Machine Type, and Reader Number.
You need to do this BEFORE installing the Card Readers onto the machines, as accessing the back of the card reader is required.

Step 4: Start Signal Connector

Connect the machine side cable to the AA3 connector on the machine control:

Step 5: Activate Card Reader

Use the provided Activation Card to activate the reader:

You must use the Activation Card for this specific location (if a reader is activated with a different location's Activation Card, it will be unable to communicate with the VAC kiosk)

Step 6: Enable the correct Machine Communication Mode

This will be Enhanced Debit mode (for Card ONLY installs), and Coin & Card mode (for Hybrid Coin+Card installs).

The machine will usually automatically enable Enhanced Debit mode once it detects a card reader is attached, but may need to be set manually on MFRxxPD model machines

For Card Only Installs:

On most Maytag machines, the machine will automatically detect the serial reader and enter enhanced debit mode when powered up.

However in some cases (MFRxxPD known to be the only one so far), you need to manually switch the machine to Enhanced Debit using the menu

For Hybrid Coin+Card Installs:

Card readers setup for Hybrid installs are NOT using serial communication, so the machine should NOT enter "Enh. Debit" mode automatically.

Instead of switching the machine to "Enh. Debit" mode, you'll instead set the machine's Coin/Debit setting to "Coin & Card"

this will allow both the coin drop, and card reader, to send pulses to the machine to trigger it to start.

By default, the machine's Coin Drop is usually connected to the Coin1 input on the machine.

Coin1's input is controlled by the "Value of Coin 1" setting, in the machine's programming menu, but the "Value of Coin 1" setting also controls how much comes off the vend price, when the machine gets a signal from Coin1 input, as well as the signal it gets from the serial port when a card reader is connected to. This has the affect of only taking $0.25 off the machine's vend price, when the Card Reader sends it's starting pulse.

There are 2 ways to get both the Card Reader and Coin Drop working with the machine:

Option 1 - Move the Coin Drop to Coin 2 Input

When our card reader is used in a Hybrid install configuration, the "Value of Coin 1" setting can be changed to equal the full vend price of the machine, in order to get the card reader to trigger the machine to start when the Card Reader is only sending 1 pulse to the machine (which is what it does by default).

However, the "Value of Coin 1" setting controls the Coin 1 input, as well as the serial input the card reader is using;

so in order to get both the card reader, and Coin Drop, working correctly in a Hybrid configuration, you would need to connect the Coin Drop to Coin2's Input, so that you can set the "Value of Coin 2" setting to equal $0.25 so the Coin Drop continues to work as intended;

then you would set the "Value of Coin 1" setting to equal the full vend price of the machine, so that 1 tap of a laundry card satisfies the full vend price, and triggers the machine to start.

Option 2 - Configure the Card Reader to send multiple pulses

The other option would be to use a different Card Reader Control Type, so that the card reader can be programmed to send multiple pulses to satisfy the vend price.

We can update the Card Reader's firmware, and use our "Quarter Multi-Pulse, No Busy [14]" Control Type in order to program the reader to send 1 pulse per quarter needed to satisfy the vend price.

To enable this type of configuratoin, contact the Laundroworks support team, as we'll need to update the card reader's firmware, and set an internal tuning paramater setting to ensure the card reader's pulses are 24ms so the machine can register the multiple pulses it receives from the Card Reader.

Below is an example of the reader settings that would be used in this type of setup:

Vend pricing

For Serial Communication card readers, the Card Reader does NOT control pricing;

pricing is set on the machine directly, and the machine updates the card reader with the correct prices to change for each cycle option.

Multi-vend pricing levels is supported with Serial communication

For Pulse Communication card readers, the Card Reader controls pricing charged to Laundry Cards.

Pricing will need to be configured via the Laundro Portal AND on the machine so that both displays match.

See our Configuring Card Reader/Machine Vend Prices article for more details on pricing these machines based on the reader communication type

Troubleshooting

Below are problems commonly encountered during installation of readers on these dryers. For more general reader troubleshooting, see Reader Support

Issue
Explanation and resolution

Reader not powering up

Confirm you've connected the cable harness using the correct sides.

Reader says "No Comm with machine"

There's no communication between the reader and the machine.

Ensure you're on Enhanced Debit mode if dealing with an older machine.

On MYR/MYS models, if you're not seeing error code D16 on the washing machine, then it is not on debit (serial) mode.
