Voltage Verification - Most G.F.C.I. Problems Are Due To Low Voltage
IMPORTANT:
IF THE VOLTAGE IS NOT WITHIN THE ACCEPTABLE RANGE, CALL AN ELECTRICIAN
OR THE LOCAL ELECTRIC COMPANY TO DIAGNOSE THE PROBLEM.
CHECK THE VOLTAGES AT:
1. Breaker Box Voltage Check
2. G.F.C.I. Line-In Voltage Check.
3. G.F.C.I. Load Out Voltage Check
4. System Box Check At Tb1
CHECK UNDER PEAK LOADS -- TWO TYPES OF PEAK LOADSUÊ
1. Spa System Peak Loads - Pumps, Heater, Blower & Light On
2. Household Peak Loads - May Be In Afternoon On Hot Day
Use Recording Meter If Possible - Records Max & Min Volts

Communication Between Topside & System Board In Most Systems
Press Button - Message Sent To System Board
System Board Performs - Message Sent Back To Topside & Relay Opens Or Closes
LED or Icon Is Turned On or Off - Hear Or See Relay Open Or Close
In Most Cases, If This Happens, There Is No Problem With The Topside Panel Or System Board

1. Press Light Button
Light LED or Icon Turns ON, But Spa Light Is NOT ON
Topside & Board Are Good, Check Downstream
Light LED or Icon Is NOT ON
Topside Or System Board May Be Bad, Continue
2. Plug In Spare Topside Panel - Easier To Check For Bad Topside
Light LED or Icon Now Turns ON
Original Topside Is Bad - R&R Topside Panel
Light LED or Icon Is NOT ON
Original Topside Is Good, Do Not Replace
System Board Is Bad - R&R System Board
3. Spa Light Is Still NOT ON - Check Downstream
Same Procedure For Other Functions
Jets, Blower, Heater, Time, Program, Mode, Etc.
Voltage Checks: Breaker Box, G.F.C.I. & System Box
When checking for proper voltage, keep in mind that the acceptable voltage range is + 10% of the recommended voltage.
Acceptable voltage when 120 V is specified is between 108 and 132 V.
Acceptable voltage when 240 V is specified is between 216 and 264 V.
Diagrams are on the following pages.
120 VOLT SYSTEMS - 120V ± 10% - 108V - 132V
240 VOLT SYSTEMS - 240V ± 10% - 216V - 264V
No More Than 2% (5 Volt AC) Difference Between Voltage
at the Breaker Panel And Voltage at the System.
