三角牌熱水器故障代碼E2:風壓異?;蝻L機故障

1當煙道被堵塞或煙道阻力太大時,風壓開關動作,程序中斷。此時可檢查與風壓開關相連的取樣管是否接插可靠、有無漏氣、有無插接錯誤等;

2當風機出現故障,轉速過低或停轉,程序中斷。此時可檢查風機同主控制板之間連接線是否插接可靠、風機是否損壞、風機是否被卡死等。

三角牌熱水器常見故障代碼有哪些:

E0進水溫度探頭問題;E1意外熄火

E2熱電偶保護;E3風壓過大

E4風機及驅動電路問題;E5高溫保護

E6出水溫度探頭問題;E7氣種開關選擇錯誤

E8二十分鐘定時保護;E9限位開關或步進電機問題

海爾熱水器維修故障代碼:

1、液晶顯示屏顯示“--”字符,開熱水閥無反應。故障原因:

(1)微動開關K不良;

(2)水壓過低或管道內堵,微動開關K無法打開;

(3)主控板損壞。

2、開水閥熱水器能工作,液晶顯示屏顯示“E1”。

故障原因:

(1)無燃氣供給;

(2)點火針H漏電;

(3)脈沖點火器D損壞;

(4)主控自吸閥ZJ1不良或由于燃氣壓力過高而未能啟動;

(5)過熱保護器CJ2不良或由于低壓壓力過高而未能啟動;

(6)高壓包輸出功率過??;

(7)過熱保護器CJ3不良或由于機械故障誤動作;

(8)過熱保護器CJ3不良;

(9)熱水器內控制板發生故障。

海爾熱水器顯示e1/e2/e3/e4故障解析:

海爾熱水器顯示e1/e2:點火失敗或中途熄火

1由于火焰檢測(反饋電極)感應電流較弱時,判定為燃燒器無火,造成程序中斷。此時可檢查反饋電極是否處于火焰的高溫區,調節反饋電極高度。
