Troubleshooting & DIY Repairs

Fix It Yourself — or Know When to Call Us

Many hot tub problems are solved with a new filter, a reset flow switch, or a replacement heater element. Others need trained technicians and diagnostic tools. This guide helps you tell the difference so you do not waste money — or make a small issue worse.

Quick Checks Before You Order Parts

• Power: Confirm the GFCI breaker has not tripped and the disconnect is on
• Water level: Low water triggers many heater and flow errors
• Filters: Dirty or clogged filters reduce jet pressure and can shut down heaters
• Air locks: After a drain and refill, burp air from pump unions if flow is weak
• Control panel: Note the exact error code or flashing pattern before resetting

Common Symptoms & Likely Causes

• No heat: Failed heater element, tripped high-limit switch, flow restriction, or bad sensor
• Weak jets: Dirty filters, closed valves, air lock, or worn pump impeller
• Pump hums but does not move water: Seized impeller, capacitor failure, or locked rotor
• Leaking: Pump seal, union o-ring, heater gasket, or cracked plumbing — locate the drip before ordering
• Control panel dead: Blown fuse on spa pack, damaged topside cable, or failed circuit board

Safe DIY Replacements

Many owners comfortably replace these with power off and water drained as needed:

• Filters and filter housings
• Cover lifters, straps, and hinges
• LED light bulbs or light assemblies
• Pump unions, o-rings, and gaskets
• Some topside control panels (model-specific — verify compatibility)

Always match part numbers to your spa brand and year. Our catalog lists OEM and compatible replacements.
