Hitachi GX series water pump runs all the time in DIY Forum Posted April 21, 2021 My Hitachi GX series WT-P 300GX2 starting to act weird. After 5 years without any problem. Now suddenly it was running all the time. To get it back to normal had to bleed air, and there was a lot of air. Then it lasted for 14 days and same procedure bleeding air again. No leaking pipes or any other signs of problems in the house. I checked all over Internet but could not find any good suggestions for my problem. Contacted a specialist in Bangkok and he new exactly what it was. He changed the "Head chamber" and when he got old one out he showed me what the problem was. See picture I attached ..._160407.jpg showing that the plastic inside head chamber is broken. Easy to fix yourself if you can isolate the pump and parts can be bought at Lazada.
