You say "Pilot" and "Flame" which isn't right with a DSI water heater. There's no Pilot. The DSI feature opens the gas valve, sparks the igniter, then the igniter serves as a "Flame Prover" to make sure it actually lit. All or nothing. No flame or full blow to heat the water. When it's come up to temperature, the gas valve closes, leaving no flame and no pilot.
Yes, I am not using correct terminology. My apologies. Then the gas valve opens, the igniter will spark, a flame will light then the gas will shut off without heating my water. This problem has progressed to the igniter not sparking regularly. The igniter has been replaced, gap checked, connections checked, corrosion cleaned. The system will try to ignite 3 times then stop. The switch inside my Clipper with the letters "DSI FLT" stays lit.
As mentioned the spark electrode is also used to prove man flame has lit.
Spark electrode MUST be 'engulfed' in main flame
When you replaced it did you position it so it was in the flame?
If it IS in path of flame then check that the wire connection is TIGHT.
Main flame generates a milivolt signal (flame ionization) that is used as PROOF flame lit.
Loose (or dirty) connection can stop that milivolt signal
Same if the ceramic insulator on electrode is cracked....signal will track to ground
