Frequently Asked Questions
Q1. What is the operating voltage of this valve?
12 V DC. This differs from most washing machine valves, which run at mains voltage. Confirm the voltage of your old valve before ordering.
Q2. My valve is 5221ER1003A, is this the replacement?
No. The A version runs at 120 V AC and this N version runs at 12 V DC. The two numbers differ by one letter and the voltage differs by a factor of ten. Read the final letter carefully.
Q3. What happens if I fit a 12 V valve to a higher voltage circuit?
The coil burns out immediately and the new part is destroyed within seconds. This is why voltage is the first thing to confirm, ahead of outlet count and ahead of physical appearance.
Q4. How do I find out my current valve’s voltage?
Read the label printed on the fitted valve, where the voltage is stated clearly. If the label is faded or worn, send us a photo of the valve and your machine model number.
Q5. My machine will not fill, should I replace the valve?
Check the inlet mesh filter, the supply tap, the supply hose and the water pressure first. A filter blocked with sediment is the leading cause of slow filling in Saudi Arabia, and cleaning it may save you the cost of a valve.
