Hot Spring spa not working? Poolburg repairs Hot Spring hot tubs across DFW, pumps, heaters, IQ 2020 controls, leaks & more. Authorized warranty service. Same-day available.
Your spa’s plua
Hot Spring is one of the most respected names in the spa industry. Built in Vista, California, these premium spas are known for their energy efficiency, innovative features, and long service life. But even the best-built spa eventually needs professional repair.
Poolburg provides expert Hot Spring spa repair across Dallas-Fort Worth. We know Hot Spring equipment, the proprietary controls, the unique heating systems, the FreshWater salt systems, and the engineering that makes these spas different from everything else on the market. Same-day service available.
mbing is its circulatory system. Water moves through pipes, valves, manifolds, and jets in a carefully designed loop. When something in that system fails, your spa leaks, loses pressure, or stops working entirely.
Poolburg specializes in spa and hot tub plumbing repair across Dallas-Fort Worth. From pinhole leaks to cracked manifolds to complete plumbing replacements, we find the problem and fix it right. Same-day service available.
Hot Spring doesn’t build generic spas. They use proprietary systems you won’t find on other brands. The IQ 2020 control system. The No-Fault heater. The FreshWater salt sanitation. The SilentFlo circulation pump. The EnergyPro insulation system. These are purpose-built components designed to work together — and when one fails, you need a technician who understands the whole system.
Our technicians have hands-on experience with Hot Spring spas across every collection and generation. From the entry-level Hot Spot to the flagship Highlife collection, from decades-old Classic models to the latest with fresh water salt systems and wireless controls, we’ve worked on them all.
When your Hot Spring needs repair, it deserves someone who knows what makes it a Hot Spring.
Highlife Collection
The flagship line. Hot Spring’s best insulation, most advanced features, and premium jet systems. Models include Grandee, Envoy, Vanguard, Aria, Jetsetter, and Prodigy. These are premium spas with premium components.
Limelight Collection
Mid-range luxury with strong features and value. Models include Pulse, Flair, Flash, Prism, Gleam, and Beam. Popular for combining Highlife technology with more accessible pricing.
Hot Spot Collection
Entry-level luxury with essential Hot Spring quality. Models include Rhythm, Relay, SX, TX, and Stride. More straightforward systems but still Hot Spring engineering.
Hot Spring Swim Spas
Dual-zone systems combining a hot tub with a swim current. Complex equipment that requires specialized knowledge.
Older & Discontinued Models
Hot Spring spas last 15 to 25 years. We service Classic, Grandee G, Landmark, Sovereign, and other discontinued models. Parts availability varies, but we work hard to keep older Hot Spring spas running.
Hot Spring uses several proprietary heating systems depending on model and year — the No-Fault heater, the Titanium heater, and integrated heater/manifold designs. When your Hot Spring stops heating, the problem isn’t always the heater itself.
Common Causes:
No-Fault heater element failed (tests fine for continuity but has an internal fault)
Circulation pump not moving water through the heater
Temperature sensor or thermistor giving false readings
IQ 2020 control board heater relay failed
Pressure switch not detecting flow
High-limit switch tripped from a genuine overheat or false trigger
What We Do:
We test the heating system from end to end — flow verification, sensor testing, heater element diagnostics, and control board output testing. We find the actual cause rather than replacing parts speculatively.
The IQ 2020 is Hot Spring’s proprietary control platform. It’s sophisticated, energy-efficient, and very different from the Balboa or Gecko systems used by most other brands. When it fails, you need a technician who understands IQ 2020 specifically.
Common IQ 2020 Issues:
Control panel unresponsive or blank
Error codes that won’t clear
Heater relay failure (common on older IQ 2020 boards)
Communication errors between the main board and accessory boards
Wireless remote connectivity problems
System won’t complete startup sequence
What We Do:
We run IQ 2020 diagnostic procedures. We test communication between boards. We check firmware versions. We identify whether the fault is in the main board, an accessory board, the topside panel, or a connected component.
Hot Spring’s SilentFlo circulation pump runs 24/7, moving water through the heater and filter continuously. It’s designed for quiet, efficient operation, but continuous duty means eventual wear.
Symptoms of SilentFlo Failure:
Spa won’t heat (no water moving through heater)
FLO error on display
Pump is silent when it should be running
Pump is noisy — grinding, humming, or rattling
Pump runs but moves very little water
What We Do:
We test power to the circulation pump, test the capacitor if applicable, and assess the pump’s mechanical condition. SilentFlo pumps can sometimes be repaired. When replacement is needed, we install the correct Hot Spring-spec pump.
Many newer Hot Spring models feature the FreshWater salt system — an integrated chlorine generator that produces sanitizer from salt dissolved in the water. It’s convenient when it works. When it doesn’t, water quality suffers.
Common FreshWater Issues:
System not producing chlorine
Cartridge life shorter than expected
Error codes related to salt system
Control system not recognizing the salt cartridge
Water chemistry difficult to maintain
What We Do:
We test the salt cartridge output, verify the controller is functioning, check water chemistry (salt level, stabilizer, phosphates), and identify whether the problem is the cartridge, the controller, or a water quality issue. We carry replacement FreshWater cartridges.
Many Hot Spring spas feature the Connextion wireless remote or the Hot Spring app for smartphone control. When connectivity fails, you lose remote control of temperature, jets, and lights.
Common Causes:
Wireless receiver module failed or unplugged
Remote battery dead or remote damaged
WiFi module lost connection to home network
Control board communication port issue
App needs update or re-pairing
What We Do:
We check the receiver module, test the remote, troubleshoot WiFi connectivity, and re-pair devices as needed. If hardware has failed, we replace it.
The Moto-Massage DX is Hot Spring’s signature jet, two moving jets that sweep up and down your back. It’s a unique feature, and it has unique failure modes.
Common Moto-Massage Problems:
Jets not moving up and down
Jets stuck in one position
Weak water flow from Moto-Massage
Mechanism noisy or grinding
What We Do:
The Moto-Massage mechanism can often be repaired by cleaning or replacing the internal components. We have experience with both the original Moto-Massage and the Moto-Massage DX.
Like any spa, Hot Spring models can develop leaks. The fully foam-insulated design, while excellent for energy efficiency, makes leak detection and access more challenging.
Common Leak Sources:
Pump shaft seals
Heater unions and gaskets
Jet body gaskets behind the shell
Light lens gaskets
Plumbing connections in the equipment bay
Drain valve not fully seated
What We Do:
We start with the equipment bay since most leaks originate there. For leaks hidden in the foam insulation, we work carefully to locate the source with minimal foam removal. We know where Hot Spring typically routes plumbing and where common leak points occur.
No-Fault Heater
Hot Spring’s proprietary heating system. Tests differently than standard elements. We know the correct diagnostic procedures.
Titanium Heater
Used in newer Hot Spring models. Corrosion-resistant but can still fail.
SilentFlo Circulation Pump
Hot Spring’s 24/7 pump. We repair and replace with correct specifications.
IQ 2020 Control System
Proprietary main boards, accessory boards, and communication protocol. Not interchangeable with generic controls.
FreshWater Salt System
Hot Spring’s integrated chlorine generation. Cartridges, controllers, and troubleshooting.
Moto-Massage DX
Moving jet mechanism. Cleaning, repair, and replacement.
EnergyPro Insulation
Fully foamed cabinets. We know how to work with foam insulation when access is needed.
Hot Spring Lighting
Lumina LED systems, exterior lights, waterfall lights.
CoverCradle & CoverCradle II
Hot Spring’s cover lifter systems. Adjustment and repair.
ACE Salt Water System
Predecessor to FreshWater. We still service ACE systems on older Hot Spring spas.

We really know Hot Spring. The IQ 2020 control system, the No-Fault heater, the SilentFlo circulation pump, the FreshWater salt system, the Moto-Massage jets, these are Hot Spring proprietary systems. A technician who only knows generic spa repair will struggle with proper Hot Spring diagnosis. We have specific training and hands-on experience with Hot Spring equipment.
Try one reset, turn the spa off at the breaker for 30 seconds and turn it back on. If the error clears and stays cleared, it may have been a transient glitch. If the error returns, call us. Error codes are your Hot Spring telling you something needs attention. Repeated resetting without fixing the cause can damage components.
With proper maintenance, a Hot Spring spa can last 15 to 25 years. The shell and structure are built to last. The equipment will need repair or replacement during that lifespan, typically starting around 7 to 12 years for pumps and heaters. The IQ 2020 control system is generally very reliable but can develop issues as it ages.
Call Hot Spring customer service and tell them you want Poolburg as your service provider in DFW. They’ll create a service dispatch and send it to us. We’ll contact you to schedule the diagnosis. If the repair is covered under warranty, you pay nothing. If something isn’t covered, we tell you before we do any work.
Yes. We service Hot Spring spas going back decades, Classic, Grandee G, Landmark, Sovereign, and earlier models. Parts availability varies for very old units. When original parts are discontinued, we find compatible alternatives or advise honestly if continued repair doesn’t make financial sense.
Circulation pump failures and heater issues top the list. The SilentFlo pump runs 24/7 and eventually wears out, typically around the 7 to 10 year mark. No-Fault heater failures are also common, especially in areas with hard water. Control board issues, particularly heater relay failures on older IQ 2020 boards, are the third most common call.
Your Hot Spring deserves a Hot Spring specialist. Call Poolburg for same-day repair across DFW.
