Asko Dishwasher Flow Meter Replacement Appliance Water Inlet Turbine Sensors
Quick Answer: A failed Asko dishwasher flow meter or water inlet turbine sensor usually triggers fill errors, low water warnings, or heater faults on D series models. Silver Instruments supplies a compatible replacement turbine sensor with a G3/4 inlet thread, a 0.2 to 5.0 L/min range, and a 5 V square wave output that matches most Asko D5424 and D5536 control boards. Send us your Asko part number, thread size, water pressure in bar, and temperature in °C for a quote within 24 hours.
Why Asko Dishwasher Flow Meter Sensors Fail
Service technicians in Australia, New Zealand, and Singapore report the same failure pattern. The turbine rotor inside the original Asko water inlet flow meter swells after long exposure to hard water and detergent residue. Calcium builds up around the rotor shaft. The Hall effect pickup stops reading pulse counts. The control board then assumes no water is entering the sump. On D5424, D5536, and D5896 machines this can set a water inlet fault or stop the heating cycle. Some units also show a low water level alarm even when the sump is full.
The original sensor is not always available as a separate spare part in Perth, Auckland, or Manila. Local appliance wholesalers often sell the complete inlet hose assembly for a much higher price. That is why repair technicians look for a compatible replacement turbine sensor. They want to keep the original hose and replace only the turbine body. We have seen this on customer sites many times.
Replacement Turbine Sensor Specifications
The SIA-WFS-05 replacement turbine sensor from Silver Instruments matches the signal expected by Asko control boards. It uses a G3/4 male inlet thread and a G3/4 female outlet thread. The rotor is PTFE coated for hard water areas. The body is glass filled polypropylene. The electronic pickup is sealed to IP65.
The SIA-WFS-05 measures 0.2 to 5.0 L/min with a K factor of 450 pulses per liter at 25 °C. Supply voltage is 5 V DC. The output is a 5 V square wave. Operating temperature range is 0 to 85 °C. Pressure rating is 0 to 10 bar. This covers cold water, hot water up to 85 °C, and standard municipal pressure in most service areas. The inlet screen protects the rotor from sand and pipe scale. The electrical connector is a three pin plug used on many Asko dishwasher harnesses.
How to Select a Replacement Flow Meter for Asko Dishwashers
Start with the part number printed on the original turbine body. Here is the thing. Asko part numbers are usually six to eight digits and vary by model year. Then check the thread size. Most residential Asko models use G3/4 but some older units use G1/2. Measure the outside diameter and thread pitch before ordering. Also check the electrical connector. Some D series units use a flat three pin plug. A few commercial Asko units use a round two pin plug. Sending us a photo of the old sensor and the wiring diagram helps our engineers confirm fitment.
This is not an original Asko part. It is a compatible replacement sensor supplied by Silver Instruments. Because we keep G1/2 adapters in stock, we can support older machines that are no longer covered by local distributors.
We saw this on a customer site in Ho Chi Minh City. A commercial dishwashing maintenance company replaced two Asko D5424 inlet sensors in March 2024. The original supplier quoted a
Installation Notes for Service Technicians
Turn off power and close the water supply before removing the old turbine sensor. Most engineers skip this part. They do not release pressure slowly and the hose can jump. Release the inlet hose pressure slowly. Remove the plastic clips from the wiring harness. Do not pull the wires directly. Unscrew the old sensor body against the hose fitting. Use a 24 mm open wrench on the flats. Wrap the threads with PTFE tape or use an EPDM washer. Finger tighten the new sensor and then turn it one half turn more. Do not overtighten the plastic body. Reconnect the harness and run a rinse cycle with the lower spray arm removed. Watch the pulse output with a multimeter if the control board still shows a fault. You should see a square wave from 0 to 5 V when the inlet valve opens.
Silver Instruments Replacement Sensors and Industrial Flow Meters
Silver Instruments supplies the SIA-WFS-05 turbine sensor for dishwasher and appliance water inlet monitoring. We also manufacture industrial flow meters for the food and beverage sector. This includes electromagnetic flow meters for CIP water lines, oval gear flow meters for liquid detergent dosing, and Coriolis mass flow meters for product batching. Our factory in Nanjing supports small batch orders for distributors and repair workshops in Southeast Asia, Oceania, Latin America, Africa, and the Middle East. The same quality control used on our industrial flow meters applies to this replacement sensor line.
For pricing or a custom thread adapter, send us your part number, thread size, water pressure in bar, temperature in °C, and the number of units you need. For industrial flow meters, also send your pipe size in DN and flow range. You can reach our sales team by Tel at +86-25-68650347, WhatsApp at +86-25-52155837, or WeChat at +86 15365082610.

FAQ
Will the SIA-WFS-05 fit my Asko dishwasher model?
It fits most D5424, D5536, and D5896 models with a G3/4 inlet turbine. Send the old part number to confirm. We also keep G1/2 adapters for older units.
What signal does the Asko flow meter send to the control board?
The turbine sensor sends a 5 V square wave pulse train. The frequency increases with water flow. The Asko board counts pulses to confirm water volume before enabling the heating element.
How do I know if the flow meter is faulty or the inlet valve is blocked?
Check the inlet valve coil resistance first. Then run a rinse cycle and measure the sensor output. No pulse signal while water flows indicates a failed turbine or a stuck rotor. Clean the rotor and retest before replacing the sensor.
Can I buy the turbine sensor without the full Asko hose assembly?
Yes. The SIA-WFS-05 is sold as a separate turbine body. You keep the original hose. This reduces part cost and lead time for repair workshops.
Do you offer OEM marking or custom connector lengths?
Yes. We offer private label marking and custom cable lengths for bulk orders above 100 units. Lead time is 7 to 10 working days for standard versions.
