If you have a DPD color match (K2005, etc) those are USELESS for diagnosing "no chlorine" problems. If you have a K2006, do the overnight bleach test, but test with BOTH the K2006 *and* an OTO drops kit. If you do NOT have the K2006 (or K1515) use only the OTO kit.

But . . . use an OTO kit no matter what!
