Introduction

It’s winter, and you’re ready for a warm, relaxing soak. But when you lift the cover, the water feels colder than it should. That’s never a fun surprise, especially on a cold day. The good news is that a chilly hot tub doesn’t always mean a big problem. With a few quick checks, you can often find out what’s wrong and stop things from getting worse.

In this guide, we’ll walk you through the most common winter hot tub problems and what you can do right away. No stress, no fuss — just simple steps to help keep your hot tub safe until everything is working again.

What You’ll Learn

In this blog, we’ll look at what to do if your hot tub has:

• A blackout
• No power
• An error code on the control panel
• A pump that won’t run
• A heater that isn’t working

Before We Start: Key Things to Know

Here are a few simple terms that will help you understand what’s going on:

• Breaker: A switch that stops electricity when there’s a problem.
• GFCI: A special outdoor breaker that shuts off power if electricity touches water.
• Control Panel: The buttons on your hot tub that let you change the jets and temperature.

Winter in Canada can be very cold. If your hot tub stops heating or circulating water, it can freeze in as little as two days — even with a good cover. That’s why it’s important to act fast. We’ll show you some easy checks you can do yourself, and when it’s time to call a professional.

Common Winter Hot Tub Problems

1. Blackout

How to Tell

• Streetlights are off
• Your home has no power
• Your phone may not make calls

What to Do

• Keep the hot tub covered to hold in heat
• If your equipment is under the steps, place a tarp or blanket over them
• Watch how long the power is out
• When the power comes back and stays on for at least five minutes, check the hot tub to make sure it starts running again

A short power outage is usually okay, but long ones can cause the water to cool fast. Keeping the cover closed helps protect your tub.

2. No Power

How to Tell

• The control panel is blank
• The jets won’t turn on

What to Check

• Look at the GFCI near the hot tub — is it tripped
• Check the breaker box inside your home

What to Do

• Find the GFCI or breaker for the hot tub
• Turn it all the way OFF
• Then turn it all the way ON
• Wait 30 seconds to see if it trips again
• Check the control panel and jets
• After one hour, check the breakers again

If the hot tub still has no power, call for service. Tell the technician:

• What you checked
• Which breaker is tripping
• How long it takes to trip

This helps us fix the problem faster.

3. Control Panel Error Code

How to Tell

• The control panel shows something other than the temperature
• It may flash between numbers or letters

What to Check

• Nothing — error codes usually mean a sensor or heater problem
• Note the water temperature

What to Do

Call for service and tell us:

• The brand and model of your hot tub
• The error code
• The water temperature

Error codes can mean many things, and winter is not the time to guess.

4. Pump Not Running

What to Check

• Is the water level high enough
• Do the jets turn on
• Does your hot tub have a separate circulation pump

What to Do

Call for service and tell us:

• The brand and model
• The water level and how fast it’s dropping
• Which pump isn’t working
• The water temperature

A pump that won’t run is serious in winter because water can freeze inside the pipes.

5. Heater Not Working

What to Check

• The water temperature

What to Do

Call for service and tell us:

• The brand and model
• The water temperature

A heater problem can cause the water to cool quickly, so don’t wait.
