It sounds as if your machine is not heating the water hot enough . This may be stopping the wash cycle if the water is not reaching temperture the tablet will not disolve and sometimes not even be added. First thing needed would be to test the machines heating element with an OHM meter. And replace the heating element if it has failed. If you do not know to use an OHM meter then you may need a hands on tech on location for this problem to be resolved.
