The Ariston 995903 Low Pressure Switch monitors water pressure within the boiler, helping the heating system operate safely and efficiently.
If system pressure falls below the required level, the switch helps prevent unsafe boiler operation. A faulty pressure switch may cause lockouts, pressure-related errors or heating problems. Replacing it with this brand-new component can help restore correct pressure monitoring and dependable boiler performance.
