How to fix an unresponsive Aqualisa QUARTZ CLASSIC Kitchen & Bath Fixtures controller with no lights?
- T
  Tracy WillisAug 22, 2025
  If your Aqualisa Kitchen & Bath Fixtures controller is unresponsive with no lights, here are a few things you can check: * Ensure the power supply to the Aqualisa SmartValveTM is turned on. A green power light should be illuminated on the Aqualisa SmartValveTM. * Check that the data cable connections are making good contact, are fully inserted, and have no visible damage, as a loss of communication could be the cause. * Verify that the wiring schematics are as per the installation instructions in the Smart Installation Guide.

  If the water temperature is too low on your Aqualisa Kitchen & Bath Fixtures, consider these possible reasons: * The hot water temperature might be too low. Check that the domestic hot water temperature is a minimum of 55ºC for stored water and 50ºC for combination boilers. * The Logic Module temperature setting might be too low. The maximum temperature is set to a factory default of 45ºC.

Why doesn't the boost button increase flow on my Aqualisa Kitchen & Bath Fixtures?
- D
  Dana HarrisonAug 31, 2025
  If the boost button on your Aqualisa Kitchen & Bath Fixtures isn't increasing the flow, here are a few potential reasons: * The combination boiler output might not meet the flow demand. Check with the boiler manufacturer for specification details. * The shower head or Aqualisa SmartValveTM could be set to ECO mode. Ensure head mode is set to normal or ECO gravity setting. * Seasonal conditions may affect performance. During the cooler months, the mains water temperature drops, which can reduce the performance of combination boilers. Check with your boiler manufacturer for details.

What causes the temperature ready display to not stabilize and the temperature to be too low in Aqualisa QUARTZ CLASSIC?
- M
  Mike AndersonSep 3, 2025
  If the controller temperature ready display doesn't stabilize and the temperature is too low on your Aqualisa Kitchen & Bath Fixtures, here are some possible causes: * There may be a hot water supply issue. Check another hot water outlet to ensure that hot water is available. * The water supplies MUST be from the same source: MUST NOT be gravity hot and mains cold. * The water supplies may be unbalanced. For mains-fed systems, the cold and hot feeds should be as evenly balanced as possible, especially for HP unvented systems. * The combination boiler might be unable to meet demand.

Why is the water temperature too hot on my Aqualisa Kitchen & Bath Fixtures?

  Kelsey BrownSep 6, 2025
  If the water temperature from your Aqualisa Kitchen & Bath Fixtures is too hot, here are a couple of potential reasons: * Seasonal conditions. In the warmer months, the mains water temperature can rise to ambient levels. The Aqualisa SmartValveTM always blends a mix of both hot and cold supplies; therefore, the output temperature at fully cold (controller setting) will always be higher than the incoming cold water supply. * Seasonal conditions (gravity-fed systems only). For installations using a cold water storage supply (gravity-fed system), the ambient temperature in the loft can rise above 40ºC, warming the stored water. Check by running a cold tap that is supplied from the water storage. Note that kitchen taps are normally fed from the mains water system.

Why does the Aqualisa QUARTZ CLASSIC controller remain illuminated after switching the shower off?
- A
  Amanda PenaSep 9, 2025
  If the controller remains illuminated after switching off your Aqualisa Kitchen & Bath Fixtures, it may be due to a poor cable connection. Check that the data cable connections are making good contact and are fully inserted, and that there is no visible damage (this includes installations where a wired remote is fitted).

Why is water dripping from my Aqualisa Kitchen & Bath Fixtures outlets after use?
- G
  Gina LambertSep 12, 2025
  Water dripping from outlets after using your Aqualisa Kitchen & Bath Fixtures can be due to: * Water retention in shower heads. * The shower heads need descaling to clear spray jets. * High pressure (unvented) water system requires servicing. Check the user guide for the hot water system to verify symptoms and where required arrange for servicing.

Why is there low or no flow from my Aqualisa QUARTZ CLASSIC Kitchen & Bath Fixtures?
- C
  Cody ThompsonNov 15, 2025
  Low or no flow from your Aqualisa Kitchen & Bath Fixtures can stem from several causes. Here are some potential reasons: * A water supply issue. Ensure the water is fully turned on at the mains and the servicing valve. * Isolation valves may not be fully open. * There might be a restriction in the waterway. (See same cause in 'Pump noisy and low / no flow' symptom.) * The hose liner could be blocked or kinked. If a flexible hose is fitted, unscrew it from the outlet connection and turn the shower on. * Incoming mains water pressure or flow might be too low (Standard Aqualisa SmartValveTM only). After confirming that the filters are clear, check with the local water authority. * A separate, stand alone pump might not be activating (Standard Aqualisa SmartValveTM only). Ensure s...

What to do if my Aqualisa QUARTZ CLASSIC pump is noisy with low or no flow?
- E
  Elizabeth LawsonNov 17, 2025
  If your Aqualisa Kitchen & Bath Fixtures pump is noisy and has low or no flow, here are potential causes and solutions: * Air lock (for Gravity fed systems only). For models utilizing an adjustable head kit; disconnect the handset from the hose, lower the hose into the shower tray or bath. Set the temperature to fully cold and then start the shower. As the water starts to flow and increase in volume gradually turn up the temperature. If the flow starts to splutter, stop moving the temperature control until the flow again stabilizes, then continue to move the dial towards the hottest setting. * Restriction in the waterway. Check for debris in the inlet filters of the Aqualisa SmartValveTM, diverter and Fixed Head connection washer. Note: The water supplies MUST be isolated when checkin...

Why am I unable to adjust or control the temperature on my Aqualisa QUARTZ CLASSIC?
- A
  Angela RyanNov 24, 2025
  If you're unable to adjust the temperature on your Aqualisa Kitchen & Bath Fixtures, consider these potential causes: * The hot and cold water supplies might be reversed. Ensure the correct water supply is connected to the specified inlet of the Aqualisa SmartValveTM. * The Logic Module of the Aqualisa SmartValveTM might have an incorrect setting. If your hot water supply is from a combination boiler, the Logic module mode MUST be set to COMBI. * There may be an airlock in the water supplies (for gravity-fed systems only). * The hot water temperature might be too high. Ensure the hot water supply temperature is below 65ºC (minimum 55ºC for stored water and 50ºC for combination boilers). * There may be a communications issue. Check the data cable connections and ensure there is n...
