1 2 3 4 POSSIBLE PROBLEM SOLUTIONS
X Lack of electricity Replace fuses or switch RCCB (30mA)
X X
Improper thermal protection Switch thermal protector or check that voltage is
correct
X Float switch disconnected Wait for water level to be back to adequate level
X X Wet end blocked Call Service Engineer
X Blocked float switch Check the free operation of the float switch
X
Disconnected discharge pipe Connect it and fix the discharge pipe correctly
X Air trapped at the pump body Move the pump laterally to empty the air
X Check valve assembled way round Assemble the valve correctly
X Pump partially covered of water Submerge the pump or wait to have the suitable level
X X Inlet filter obstructed Clean the suction filter
X
Total manometric head higher than
expected Check the geometric head and loss of head
X Impeller worn Contact a Service Engineer
X Deteriorated discharge pipe Replace it by a new one
