Pentair EasyTouch Self Test Error Codes

The EasyTouch Self Test feature is a diagnostic tool that checks control panel hardware. After running the test, an error code indicates whether problems were detected.

This test is primarily intended for service personnel to diagnose control panel issues.

Running the Self Test

1. Press Menu button on EasyTouch control panel
2. Navigate to Diagnostics
3. Select Self Test
4. Follow on-screen prompts to test LCD and buttons
5. When complete, an error code is displayed

Note: Testing displays "CODE: 0" for successful test or a numbered code for errors.

Error Code Reference

Code	Description	Problem Area
Code 0	PASS - No problems	Control panel functioning normally
Code 1	LCD backlight	Backlight not functioning properly
Code 2	LCD contrast	Display contrast issue
Code 3	LEDs	One or more LEDs not working
Code 4	Switch (buttons)	One or more buttons not responding
Code 5	UART loopback test	Communication circuit issue
Code 6	Sensor/Relay/Valves test	Output control circuit issue

Multiple Error Codes

If multiple problems are detected, multiple codes are displayed. For example, "Codes 4, 2, 1" indicates problems with buttons, LEDs, and LCD backlight.

Troubleshooting Each Code

Code 1: LCD Backlight

Symptoms: Display is dim or not illuminated

Possible causes:

• Failed backlight LED
• Backlight driver circuit failure
• Power supply issue

Solution: Control panel may need replacement

Code 2: LCD Contrast

Symptoms: Display appears washed out or too dark

Possible causes:

• Contrast adjustment circuit failure
• LCD panel degradation

Solution: Control panel may need replacement

Code 3: LEDs

Symptoms: Status LEDs near buttons don't illuminate properly

Possible causes:

• Failed LED
• LED driver circuit issue

Solution: Control panel may need replacement

Code 4: Switch (Buttons)

Symptoms: Buttons don't respond when pressed

Possible causes:

• Failed button contact
• Debris under button membrane
• Water damage

Solution:

1. Clean button membrane surface
2. Check for water intrusion
3. Control panel may need replacement if cleaning doesn't help

Code 5: UART Loopback Test

Symptoms: Communication issues between panels

Possible causes:

• Communication chip failure
• Board-level circuit issue

Solution: Control panel or motherboard may need replacement

Code 6: Sensor/Relay/Valves Test

Symptoms: Equipment not responding to commands

Possible causes:

• Output driver failure
• Relay control circuit issue

Solution: Motherboard may need replacement

When Self Test Won't Run

If the self test won't start:

• Verify control panel has power (display should show something)
• Check wiring between control panel and load center
• Try power cycling the system

Post-Test Actions

• Code 0: Panel is working correctly; look elsewhere for problems
• Other codes: Document the codes and contact Pentair support or replace panel
