If your Wilo Water Pump isn't running despite being switched on, there might be a power issue. First, check the electrical fuses. If the fuses are fine, ensure the pump is receiving voltage and resolve any power interruptions.
Why is my Wilo Stratos PICO-Z Water Pump not maintaining the set minimum flow?
If your Wilo Water Pump isn't maintaining the set minimum flow, there are several possible reasons: * The piping might be partially or completely blocked. Open valves in the piping to resolve this. * The piping could be undersized, requiring a change in the piping design. * Open taps may be affecting the flow. Close the taps and check if the pump reaches the minimum flow. * Cold water may be flowing into the circulation pipe. Install non-return valves to prevent this.
Why does my Wilo Stratos PICO-Z Water Pump display a temperature much higher than the set minimum?
If your Wilo Water Pump displays a current temperature much higher than the set minimum, it could be due to: * The temperature on the heat generator being too high compared to the set minimum temperature on the pump. Adjust the settings of the heat generator and pump to match. * The set minimum flow having priority over the set minimum temperature, preventing the pump from running more slowly. Check the set minimum flow.
What to do if my Wilo Stratos PICO-Z Water Pump is not reaching the set minimum temperature?
If your Wilo Water Pump isn't reaching the set minimum temperature, consider the following: * The storage tank temperature may be too low. Check it and increase if necessary. * Open taps could be the cause. Close them and check if the pump then reaches the minimum temperature. * Cold water might be flowing into the circulation pipe. Install non-return valves. * Excessive heat losses may be occurring due to inadequate piping insulation. Insulate the piping or check the existing insulation.
Why is my Wilo Stratos PICO-Z Water Pump making noises?
If your Wilo Water Pump is making noises, it could be due to: * Cavitation, caused by insufficient suction pressure. Increase the system pressure within the permissible range. * The delivery head might need adjustment. Check the delivery head and set it to a lower head if necessary.
What to do if my Wilo Stratos PICO-Z is running but there is no circulation?
If your Wilo Water Pump is running but there's no circulation, the circulation pipe may not be filled or vented. Fill and vent the circulation pipe to resolve this issue.
What does E11 Dry running warning mean on my Wilo Stratos PICO-Z?
The E11 Dry running warning on your Wilo Water Pump indicates there may be air in the pump. Check the volume flow and water pressure.
Why is my Wilo Water Pump not detecting thermal disinfection?
If your Wilo Water Pump isn't detecting thermal disinfection, it may be because the pump's self-learning phase (24 hours of uninterrupted operation) was not observed. Activate thermal disinfection and allow the pump to complete its self-learning phase.
What does LED E04 Undervoltage fault mean on my Wilo Water Pump?
The LED E04 Undervoltage fault on your Wilo Water Pump indicates that the power supply is too low on the mains side. Check the mains voltage.
What does E05 Overvoltage mean on my Wilo Stratos PICO-Z Water Pump?
The E05 Overvoltage error on your Wilo Water Pump means the power supply is too high on the mains side. Check the mains voltage.
