About this fuse

The Allied Innovations 218 Series 0218.500HXP is a precision time-lag fuse designed for spa and hot tub electrical systems. This 5×20mm fuse provides reliable overcurrent protection for pumps, heaters, and control circuits in residential and commercial spa applications. The time-lag design allows temporary current surges during motor startup while protecting against sustained overloads that could damage sensitive spa components.

Built to OEM specifications, this exact-fit replacement fuse ensures your spa's electrical system operates safely and efficiently. Every 218 Series fuse ships same-day from our Canadian warehouse and includes our 1-year warranty for complete peace of mind. Always verify your existing fuse's amperage rating and physical dimensions before installation, and ensure power is completely disconnected before replacing any electrical components in your spa system.

Common symptoms this part fixes

If your spa is showing any of these signs, this part is likely your fix:

  • Spa control panel completely dead with no display
  • Spa powers off unexpectedly and will not restart
  • Specific circuit (pump, heater, or blower) fails to respond
  • OEM fuse holder shows a blown or discolored fuse element
  • Spa throws a fault code related to a control board circuit failure

Not sure if this is your problem? Try our diagnostic centre or .

Before you buy — quick checklist

  • Confirm the blown fuse reads 500mA (0.5A) — amperage is printed on the fuse end cap or body
  • Confirm physical dimensions are 5mm x 20mm before ordering
  • Verify the time-lag (slow-blow) designation — do not substitute a fast-blow fuse in a time-lag application
  • Inspect the fuse holder and surrounding board for burn marks or damage — a repeatedly blowing fuse indicates an underlying fault that must be diagnosed before replacement
  • Disconnect all power to the spa at the breaker before accessing the control box

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
