If your P5D PWM pump is working but the controller is still alarming, it could be due to a sensor misread or firmware glitch rather than an actual malfunction. Make sure the RPM signal wire is properly connected, as missing or fluctuating RPM readings can trigger false alarms. Also, check for firmware updates or try resetting the controller. It's a common tech hiccup—sometimes things function fine but still throw errors, much like navigating a big shopping spot like Bugis Junction https://bugisjunctionsg.com/ , where everything's running smoothly even if a sign or two seems off. A quick inspection and reboot may solve the issue.
