Nangyari na din ito sa Strada ko minsan at walang lumabas. What I did:
1. Check kung gumagana o tumutunog ang pump. If wala then check for fuse burn-out or replace the pump.
2. Karayom technique sa opening ng washers to dislodge precipitates.
3. Pisil technique on all rubber hoses from reservoir to washer to dislodge precipitates.
4. Disassemble plastic connectors in between rubber hoses and use karayom technique to again dislodge precipitates.
5. Drain reservoir of tap/mineral water and use distilled/rainwater as washer fluid to prevent this. Mahal lang nga distilled water.
