Professional Hot Tub Repairs & Fault Diagnosis

Hot tub repairs from £80 inc VAT

When something goes wrong with your hot tub, identifying the cause is the first step towards getting it working again.

Some problems are immediately obvious, such as a leak or a pump that has stopped running. Others may involve the heating system, water circulation or electrical components.

MG Hot Tubs provides fault diagnosis and repair services to identify the source of the problem and determine the work required.

We have access to replacement parts and diagnostic equipment to support repairs across a range of hot tub systems.

Common Hot Tub Problems We Can Investigate

Hot Tub Not Heating

If your hot tub is struggling to reach or maintain its set temperature, there may be an issue with the heating system, water circulation or associated components.

A professional inspection can help establish what is preventing the water from heating correctly.

Hot Tub Pump Problems

A faulty pump can affect water circulation, jet performance and the general operation of your spa. If your pump is making unusual noises, has stopped working or is not providing normal water flow, MG Hot Tubs can investigate the problem and advise on the appropriate repair.

Hot Tub Leaks

Water leaks can develop around pipework, fittings, seals and other components. Locating the source is important before attempting repairs, particularly where water is escaping inside the equipment cabinet.

Hot Tub Electrical Faults

Electrical problems may affect the control system, heating, pumps or other functions. If your hot tub is displaying error messages, tripping the electrical supply or failing to operate correctly, it should be assessed before further use.

Hot Tub Control Panel & Error Messages

An error code or unresponsive topside control panel can indicate a range of possible issues. Providing details of the displayed error and your hot tub model can help with the initial enquiry.

Fantastic service from Ben who came to service our hot tub which had been out of use for some time. He worked non stop, including through the rain, to get it up and running and looking great! He and Marcus provided lots of useful advice on how to keep it maintained and what products we needed as first time hot tub owners. MG Hot Tubs will be our go to for future servicing and maintenance. Highly recommended! ⭐️⭐️⭐️⭐️⭐️
