Pressure Sensor Error

What This Means

Pressure sensor assembly out of order; Water level frequency consistently below 10 kHz or over 30 kHz; Pressure sensor connector broken or loose; Pressure sensor resistance out of range (pin 1 to pin 3 should be 21-23 Ohm ±10%); Air chamber and tube clogged

How to Fix

1. 1

   Confirm PE is displayed. Note: PE will NOT disappear when START/PAUSE is pressed — it does not enter pause mode

2. 2

   Check if pressure sensor connector is broken or loose. Reconnect or repair if so

3. 3

   Measure resistance of pressure sensor (pin 1 to pin 3, should be 21-23 Ohm ±10%). Replace pressure switch if out of range

4. 4

   Check if AIR CHAMBER and tube are clogged. Fix air chamber and remove foreign material if clogged

5. 5

   If all checks pass, replace MAIN PWB ASSEMBLY
