⚡ Cal Spas BP501G1 Spa Circuit Board — ELE09907297 — Patio & Escape Series 2-Pump Spa Control

OEM-quality Cal Spas BP501G1 replacement board for reliable multi-pump spa control and performance.

⚠️ IMPORTANT — PLEASE READ BEFORE ORDERING

• Identify by chip number and board number. Your existing board’s white sticker should show chip BP501G1R1E (or an earlier revision ending in a different letter such as R1D). The Balboa board number 56488 will also appear on the sticker. Confirm both before ordering.
• This board supports 2-pump systems without a circulation pump. If your Cal Spas system uses a 2-speed Pump 1 together with a circulation pump, that system requires the BP501G2 board instead — not the BP501G1.
• Non-returnable. Cal Spas circuit boards cannot be resold as new to another owner. Confirm compatibility before ordering.
• Upgraded design. The ELE09907297 has been redesigned with upgraded relays and circuitry compared to earlier revisions. This improves long-term reliability over the boards it replaces.
• 120V operation is limited. This board is primarily a 240V system. A 120V configuration is only available in Setups 5 and 6 (single-pump, no Pump 2 or Blower). For most Cal Spas Patio and Escape series 2-pump installations, 240V service is required.

📋 Product Overview

The Cal Spas BP501G1 circuit board (Cal Spas OEM part number ELE09907297, Balboa board number 56488, chip BP501G1R1E) is a factory-original Cal Spas replacement PCB manufactured by Balboa Water Group.

🔍 Error Codes & Diagnostics

Setup Change Confirmation: After changing a Setup, press “Clear” if the display shows “The settings have been reset” — this is normal and expected when changing Setups with S1 switch 6 in the OFF position.

Test Mode: Move S1 switch 1 to ON while the system is running. Temperature display will show “T” instead of °F or °C to confirm Test Mode is active.

❓ Frequently Asked Questions

Q: How do I confirm this is the right board for my Cal Spa? A: Check the white sticker on your existing circuit board. The chip number should show BP501G1R1E (or R1D for older boards). The Balboa 5-digit number 56488 should also appear. Both confirm this is the correct Cal Spas OEM replacement.

Q: My Cal Spa has a 2-speed pump AND a circulation pump — is this the right board? A: No. A 2-speed Pump 1 with a separate circ pump requires the BP501G2. The BP501G1 does not support that combination. Contact Parts4Tubs to confirm which board is correct for your system.

Q: What Setup should I use? A: The Setup number for your spa should be written on a label inside the system lid. If it’s not there, match your pump/blower/circ configuration to the Setup Reference Table above. The board ships in Setup 1.

Q: Can I use a 120V outlet with this board? A: Only in Setups 5 and 6 (single-pump, no Pump 2 or Blower). Most Cal Spas Patio and Escape series 2-pump systems run on 240V and require the standard 48A / 60A max breaker service.

Q: Is there a universal replacement board available? A: Yes — the BP501U (Balboa PN 33-59375-K) is a universal replacement that covers all BP501Gx board variants. Contact Parts4Tubs if you want to explore this option.

Q: What warranty is included? A: 1-year manufacturer warranty (Balboa Water Group). Contact Parts4Tubs for full warranty terms.

🔌 Summary

The Cal Spas BP501G1 circuit board (ELE09907297, chip BP501G1R1E, Balboa board 56488) is a factory-original OEM replacement for Cal Spas Patio and Escape series hot tubs with the BP501G1 control system. Built on Balboa’s BP Series platform with M7® dual-sensor technology, it supports 2-speed or 1-speed Pump 1, 1-speed Pump 2 or Blower, ozone, spa light, and up to 5.5kW electric heating at 240V. Key restriction: this board does not support a 2-speed Pump 1 paired with a circulation pump — that requires the BP501G2. Standard service is 240VAC / 48A / 60A max breaker. The board ships in Setup 1; confirm your spa’s Setup from the label inside the system lid and set S1 switch 6 to OFF upon final installation.

Finding and identifying a replacement Hot Tub Circuit Board (PCB)

If you are looking to replace a failed PCB on your Hot Tub’s spa pack, then quite often identifying the part that you need can be the hardest thing.

Firstly, you are looking for a model number on the actual circuit board itself. Having the model or serial of your hot tub is not going to help at this point, you need to find the number on the PCB itself.

Now, with certain brands of PCB, the number of the replacement PCB that you need is not going to match identically the one you are replacing. Why is that I hear you ask?

Well, normally, it is an updated version. This means that it might have updated firmware on the PCB or be a later revision. Normally, this means that the part number would be slightly different. This is usually indicated with a “12345678 -x” at the end of that part number where x indicated a firmware revision.

In some cases, there will be some following letters on the part number of the circuit board, “12345678 -x MAS” this can indicate that the PCB was used for an OEM meaning it was produced for a certain hot tub manufacturer and the letters identify the manufacturer.

This means if you source an original PCB, it will not have the letters, but will in most cases work just fine.

It can be confusing I know!

What if you can’t find a model number?

If you can’t find a model number on the PCB itself, then you need to look for a model number on the spa pack. Normally, there is a sticker on the outside of the spa pack that tells you the current ratings and input voltages etc and this will have a model number.

In general, most spa packs in the USA are manufactured by Balboa, Hydro-Quip, ACC or Gecko. I know I am generalising here, but if you have a spa pack that has the brand of your hot tub on, it will be an OEM so the key is identifying who made the original box.

From there, you can normally find an original PCB that you will be able to switch out.

For example, the Balboa VS (value series) is a very popular spa pack that has been used by multiple hot tub manufacturers under their own brand names. Whatever they have called it, strip it back and it is still a Balboa VS.

Visual Inspection

One of the most important things you can do when you are looking for a replacement is to visually inspect the PCB that you have versus the picture online of the replacement you are considering. They need to look the same even if there are the differences in firmware revisions or OEM part numbers, you should be visually replacing a PCB that looks like the one you have.

Configuring a replacement Hot Tub Circuit Board (PCB)

When you get a new PCB, you are more than likely going to need to configure it. Most PCBs have a number of different modes and setups that the can operate in. For this, you will need to manual or spec sheet to guide you.

For things like DIP switches, most of the time you can copy the settings from your original circuit board. You are looking for things like setting the voltage as a lot of PCBs can be configured to run on both 115V and 230V.

You may need to move jumpers or even wires to configure voltages – the key here is that you read the schematic and don’t expect the PCB to just work out of the box – it usually doesn’t.

Troubleshooting a Hot Tub Circuit Board (PCB)

Here are some common things you will see when you replace a PCB on a hot tub.

You press the buttons on the topside control and they don’t control the right parts (pumps or blower etc) – this is a mode configuration thing and you will either need to change some DIP switches on the PCB or an internal or low level programming mode on the topside control. Check the manual for how to do this.

You turn on the hot tub and it trips the breaker – it is not common for a new PCB to fail out of the box (I have not seen one yet!) However, a common mistake is that the voltage has not been set correctly. If it is set for 115V and then you try and turn it on, the current draw will be a lot more (twice) than expected and the breaker will trip.

To check this, unplug all of your kit – heater, pumps, blower and then turn on the PCB. If it trips with nothing plugged in, usually the voltage is incorrectly set and what is happening is that live current is being sent to the ground – because you have 4 wires into the PCB rather than 3. Current on the ground loop causes the trip. Check the settings to make sure it is configures for 230V.

It might not trip until you physically turn on a pump or a blower. As mentioned, if the pack is set to 115V and your pump is meant for 230V, it will draw twice the current at half the voltage and trip your breaker. Check the manual for info on how to set the voltage.
