Aqualisa Shower Pump Not Working — Troubleshooting Guide
Check the steps below first — if you're not confident, get it fixed safely today.
Post a job — we'll find you an engineer →Aqualisa pumped shower systems integrate the pump with the shower unit — isolate at both the fused spur and the water isolation valves before inspection.
Aqualisa pumped shower systems are brilliant when they work, but a loss of pressure or flow can be genuinely frustrating—especially when you've invested in a premium unit. These showers are engineered as complete systems where the pump, valve, and controls work together, which means troubleshooting is slightly different from retrofitted pump setups. Most problems stem from simple issues: closed isolation valves, blocked heads, kinked hoses, or airlocks—all of which you can investigate yourself with basic checks. However, because Aqualisa systems are integrated units, internal faults like solenoid valves or flow switches really do need professional attention, and that's when the manufacturer's service team becomes your best friend.

Most likely cause & what to check
Aqualisa (aqualisa.co.uk) is a UK shower specialist. Their pumped shower ranges include the Aquastream (negative head capable) and the Turbostream. Unlike third-party pumps fitted to any shower, many Aqualisa systems are designed as complete units where the pump is integral or closely matched to the shower valve. Installation and fault manuals can be downloaded from aqualisa.co.uk under Product Support.
No water or very low flow: check the isolation valves on both hot and cold supplies are fully open. On Aqualisa systems, there are often isolation valves built into the pump body or the shower valve assembly — make sure all are open.
Aqualisa Aquastream not starting: the Aquastream uses a negative head flow switch that activates when the shower handle is turned. If it doesn't start, the flow switch or solenoid valve inside the unit may be faulty. This is an internal component — Aqualisa recommend calling their service line rather than attempting DIY repair.
Aqualisa pump making noise: vibration and noise often come from the pump mounting. Check that the pump is securely fixed to the wall and all hoses have sufficient loops (not pulled taut). Replacement anti-vibration mounts are available from Aqualisa directly.
Aqualisa Turbostream cutting out: check for a blocked shower head or kinked outlet hose. The Turbostream has a thermal cutout — if it trips repeatedly, check for airlock or blockage as described above.
Aqualisa have a dedicated UK customer service and technical helpline — 01959 560010 — and offer a repair/replacement service for out-of-warranty units. Given the integration of Aqualisa systems, professional servicing by an Aqualisa-approved installer is often the most cost-effective route for complex faults.

Frequently asked questions
Why has my Aqualisa shower suddenly lost pressure?
The most common cause is a closed isolation valve on the hot or cold supply—these are often tucked away in the pump body or valve assembly and can accidentally get turned off. Check both supply valves are fully open, then look for blockages in the shower head or kinks in the outlet hose. If neither of those fixes it, you may have an airlock in the system, which usually clears itself after running the shower for a few minutes.
Is it safe to take apart my Aqualisa shower pump myself?
No—Aqualisa recommend leaving internal repairs to professionals because the pump integrates closely with the valve and control systems. Before you even inspect the unit, always isolate it at the fused spur (electrical) and both water isolation valves (to prevent flooding). If the fault involves internal components like solenoid valves or flow switches, call Aqualisa's technical helpline on 01959 560010 rather than risking damage.
What should I do if my Aqualisa pump keeps cutting out?
First, check for a blocked shower head—a clogged nozzle forces the pump to work harder and can trigger a thermal cutout. Next, inspect the outlet hose for kinks or tight bends, and look for signs of an airlock (irregular flow or sputtering). If the pump cuts out after just a few minutes every time, contact Aqualisa technical support, as this suggests an internal thermal protection issue.
Why is my Aqualisa shower pump making a loud noise or vibrating?
Vibration and noise usually mean the pump isn't secured properly to the wall—check all fixings are tight and haven't worked loose over time. Examine the inlet and outlet hoses too; if they're pulled taut or routed badly, they can transmit vibration. Aqualisa sell replacement anti-vibration mounts that dampen these issues effectively, and they're worth fitting if noise persists after checking brackets and hose routing.
