excel cartridge whistles

Cartridge is set to High Pressure, been fine for over 5 years, but now when set to mid range say 4-5 on temp it whistles quite loudly yet turn temp down it stops, turn temp up it stops...plus its now weeping from behind it somewhere, is it simply shot it? It is a true power shower in that the 3 bar pump twin impellor pump is gravity fed both hot and cold, NOT from mains pressure, flow is still excellant, just this noisy whistle. will a replacement cartrdge cure it?

If you have problems with an Excel then it's best just to replace the cartridge, however it is probably worth stripping the cartridge out and checking that the inlet filters are clean, before buying a new cartridge.

Purchased a new cartridge from you. We have a combi boiler so cartridge set to high setting. The plumber has had to come back on three occasions to get the temp right. Having sorted this out the shower now has a high pitch whistle. Have checked the new filters and they are fine. What can I do to get rid of this noise. Could it be a faulty cartridge. The old cartridge did not whistle.
