The Ultimate Hot Tub Maintenance Schedule: Daily, Weekly and Monthly Tasks
Regular hot tub maintenance does not need to take hours. A few consistent checks can help prevent cloudy water, blocked filters, poor circulation and expensive equipment problems.
The right routine depends on how often the hot tub is used, but most owners can keep things under control by following a simple daily, weekly and monthly schedule.
Why Hot Tub Maintenance Matters
Hot tub water is warm, aerated and used by multiple bathers. This means body oils, cosmetics, dirt and other contaminants can build up quickly.
Without proper maintenance, you may experience:
- Cloudy or foamy water
- Unpleasant smells
- Dirty or blocked filters
- Reduced water flow
- Heating problems
- Scale around jets
- Premature wear to pumps and components
Regular checks help identify small issues before they develop into more expensive repairs.
Before Using Your Hot Tub
Carry out a quick visual check before getting in.
The water should be clear enough to see the bottom easily. Do not use the hot tub if the water is cloudy, green, slimy or has an unusual smell.
Also check:
- The water temperature
- The water level
- The control panel for error messages
- Whether the jets and circulation appear normal
If the water level is too low, the system may draw in air and circulation may be affected.
Daily Hot Tub Maintenance
Daily maintenance is mainly about spotting changes early.
Check the Water
Look for changes in colour, clarity or smell. A strong chemical smell can indicate that the sanitiser has reacted with contaminants rather than that there is too much chlorine.
Test the water rather than relying on smell alone.
Remove Debris
Use a clean spa net to remove leaves, insects or other floating debris before it reaches the filter.
Check the Cover
Make sure the cover is correctly positioned when the hot tub is not in use.
A good cover helps:
- Reduce heat loss
- Keep out rain and debris
- Protect the water from sunlight
- Lower unnecessary energy use
Remove standing water and debris from the cover carefully.
Weekly Hot Tub Maintenance
Weekly tasks form the most important part of your maintenance routine.
Test the Water
Test the sanitiser, pH and total alkalinity using suitable test strips or a water-testing kit. Follow the recommended levels for your hot tub, sanitiser system and chemical products. Make small adjustments where possible, allow the water to circulate and retest before use.
Shock the Water
Shock treatment helps break down contaminants that normal sanitiser levels may not remove.
It may be needed:
- After heavy use
- When the water looks dull
- When there is a strong smell
- When sanitiser levels have dropped
- As part of your normal chemical routine
Always follow the product instructions and wait until the water is safe before using the hot tub.
Rinse the Filters
Remove the filters and rinse between the pleats using clean water.
Do not use washing-up liquid, household cleaning sprays or a pressure washer. These can contaminate or damage the filter.
Filters may need more frequent attention if the hot tub is used heavily or surrounded by dust, leaves and garden debris.
Wipe the Waterline
Body oils and cosmetics often collect around the waterline.
Use a soft cloth and a cleaner approved for hot tub surfaces. Regular cleaning prevents a greasy ring from becoming difficult to remove.
Check the Jets
Turn on the jets and check that water flow feels normal.
Weak flow may be caused by:
- A dirty filter
- Low water level
- A closed jet
- An air lock
- A circulation problem
If simple checks do not solve the issue, arrange a professional inspection.
Monthly Hot Tub Maintenance
Deep-Clean the Filters
Use a specialist filter cleaner periodically, following the instructions carefully. Rinse the filter thoroughly before returning it to the hot tub, as leftover cleaning product can cause foam. Replace filters that are damaged, misshapen or remain blocked after cleaning.
Clean and Inspect the Cover
Check the cover for:
- Cracks or damaged stitching
- Broken straps or handles
- Waterlogging
- Mould underneath
- Loss of shape
A heavy or damaged cover may no longer insulate the hot tub effectively.
Look for Leaks or Unusual Noise
Inspect the cabinet, ground and visible pipework for dampness.
Also listen for unusual vibration, grinding or changes in pump noise. Persistent leaks or mechanical noise should be investigated early.
Every Three to Four Months
Most domestic hot tubs need to be drained and refilled periodically, although the timing depends on usage and water quality. Before draining, use an approved pipe cleaner if suitable for your system.
Then:
- Turn off the power.
- Drain the water correctly.
- Clean the shell and fittings.
- Rinse or replace the filters.
- Refill following the manufacturer’s instructions.
- Restart the system.
- Test and balance the fresh water.

Seasonal Maintenance
Summer
Warmer weather and heavier use can increase sanitiser demand. Test the water more frequently, keep the cover closed when the hot tub is not in use and clean the filters regularly.
Autumn and Winter
Remove leaves promptly and monitor the water after heavy rain. If the hot tub will remain full during winter, it must stay powered and protected from freezing. Simply draining the visible water and switching it off can leave water trapped in the pipework. Arrange professional winterisation if the hot tub will not be used.
